  • Ajax Request using jQuery in Rails

    - by Steve
    Hi... I am sending an Ajax Request using jQuery. What happens is that I am getting an "405 Method Not Allowed" Error. I am just posting a form, which would get the detail from the form and insert it into the DB. Just the usual stuff.I am using WEBrick that comes as default with the rails package. Can somebody please tell me how to fix this. This is the code that triggers the Ajax Request $.post($(this).attr("action") + ".js",$(this).serialize(),null,"script"); Response Headers Cache-Control no-cache Allow GET, PUT, DELETE Content-Type text/html; charset=utf-8 Content-Length 9502 Server WEBrick/1.3.1 (Ruby/1.9.1/2009-12-07) Date Wed, 02 Jun 2010 20:41:33 GMT Connection Keep-Alive Request Headers Host localhost:3000 User-Agent Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept application/json, text/javascript, */* Accept-Language en-us,en;q=0.5 Accept-Encoding gzip,deflate Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive 115 Connection keep-alive Content-Type application/x-www-form-urlencoded; charset=UTF-8 X-Requested-With XMLHttpRequest Referer http://localhost:3000/viewspot/3 Content-Length 141 Pragma no-cache Cache-Control no-cache

  • C# ...extract email address from inside 100's of text files

    - by Developer
    My SMTP server got 100's of errors when sending lots of emails. Now have lots of .BAD files each one containing an error message and somewhere in the middle, the actual email address it was supposed to be sent to. What is the easiest way to extract from each file "just" the "email address", so that I can have a list of the actual failed emails? I can code in C# and any suggestion will be truly welcomed.

  • PHP Array saved to Text file

    - by coffeemonitor
    I've saved a response from an outside server to a text file, so I don't need to keep running connection requests. Instead, perhaps I can use the text file for my manipulation purposes, until I'm read for re-connecting again. (also, my connection requests are limited to this outside server) Here is what I've saved to a text file: records.txt Array ( [0] => stdClass Object ( [id] => 552 [date_created] => 2012-02-23 10:30:56 [date_modified] => 2012-03-09 18:55:26 [date_deleted] => 2012-03-09 18:55:26 [first_name] => Test [middle_name] => [last_name] => Test [home_phone] => (123) 123-1234 [email] => [email protected] ) [1] => stdClass Object ( [id] => 553 [date_created] => 2012-02-23 10:30:56 [date_modified] => 2012-03-09 18:55:26 [date_deleted] => 2012-03-09 18:55:26 [first_name] => Test [middle_name] => [last_name] => Test [home_phone] => (325) 558-1234 [email] => [email protected] ) ) There's actually more in the Array, but I'm sure 2 are fine. Since this is a text file, and I want to pretend this is the actual outside server (sending me the same info), how do I make it a real array again? I know I need to open the file first: <?php $fp = fopen('records.txt', "r"); // open the file $theData = fread($fh, filesize('records.txt')); fclose($fh); echo $theData; ?> So far $theData is a string value. Is there a way to convert it back to the Array it originally came in as?

  • IIS7 dynamic content compression and webservices

    - by vandalo
    I am moving and old asmx webservice to a new server with IIS7. This webservice basically sends a big dataset (10mb+) to a winform application. The old solution was implemented using a custom soap extension which compressed the content before sending the stream to the client. The client, of course, implemented the same custom soap extension, to decompressed the stream in a dataset. Everything has worked pretty well for years. My customer doesn't want to change the code upgrading to WCF. They just want to put the old App on the new server and use the new dynamic content compression features. We're testing things on a test server (win serv 2008) and it seems that it's working pretty well, even if it seems slow: we can't see any difference in performance (speed) between the uncompressed and compressed stream. Here's the question. Where should I put the settings? Most people say I can't put it in my web.config; others say it can be put there. I am a bit confused. Are there any tricks or things I should know? What about mimeTypes? Should I set some parameters, somewhere? ... considering my stream is XML (dataset) ?? Thanks to everyone who would like to help Alberto

  • UDP server doesnt accept calls from outside.

    - by rayman
    Hi, ive implement simple udp server on my Android device.(sdk 1.5) it works fine when i am runnning a local client on the phone sends through it trigger to my server. but when i try to get udp call from an outside server to my phone, it doesnt work. already make sure the outside server isnt blocked by firewall and it's sending the udp trigger to the right port, which my phone is listening to. i used natstat on the phone and checked that the phone is realy listening to the it's local ip and the port ive setted it to. here is my code of the server:(on the device) // server will listen to one client try { Thread udpServerThread = new Thread() { @Override public void run() { try { // Retrieve the ServerName InetAddress serverAddr = InetAddress .getByName("localhost"); Log.d("UDP", "S: Connecting..."); // Create new UDP-Socket socket = new DatagramSocket(SERVERPORT,serverAddr); byte[] buf = new byte[17]; // * Prepare a UDP-Packet that can contain the data we // * want to receive DatagramPacket packet = new DatagramPacket(buf, buf.length); Log.d("UDP", "S: Receiving..."); // wait to Receive the UDP-Packet socket.receive(packet); Log.d("UDP", "S: Received: '" + new String(packet.getData()) + "'"); acceptedMsg=new String(packet.getData()); notifyService(acceptedMsg); Log.d("UDP", "S: Done."); } catch (Exception e) { Log.e("UDP", "S: Error", e); } } }; udpServerThread.start(); } catch (Exception E) { Log.e("r",E.getMessage()) ; } so as i said, when i try it with local client(seperate thread) which sends udp trigger it works fine, but when i take this client implementation and put it on an outside real server, after UDP being sent, the phone doesnt respond to it. any idea? thanks, ray.

  • How can I send GET data to multiple URLs at the same time using cURL?

    - by Rob
    My apologies, I've actually asked this question multiple times, but never quite understood the answers. Here is my current code: while($resultSet = mysql_fetch_array($SQL)){ $ch = curl_init($resultSet['url'] . $fullcurl); //load the urls and send GET data curl_setopt($ch, CURLOPT_TIMEOUT, 2); //Only load it for two seconds (Long enough to send the data) curl_exec($ch); //Execute the cURL curl_close($ch); //Close it off } //end while loop What I'm doing here, is taking URLs from a MySQL Database ($resultSet['url']), appending some extra variables to it, just some GET data ($fullcurl), and simply requesting the pages. This starts the script running on those pages, and that's all that this script needs to do, is start those scripts. It doesn't need to return any output. Just the load the page long enough for the script to start. However, currently it's loading each URL (currently 11) one at a time. I need to load all of them simultaneously. I understand I need to use curl_multi_*, but I haven't the slightest idea on how cURL functions work, so I don't know how to change my code to use curl_multi_* in a while loop. So my questions are: How can I change this code to load all of the URLs simultaneously? Please explain it and not just give me code. I want to know what each individual function does exactly. Will curl_multi_exec even work in a while loop, since the while loop is just sending each row one at a time? And of course, any references, guides, tutorials about cURL functions would be nice, as well. Preferably not so much from php.net, as while it does a good job of giving me the syntax, its just a little dry and not so good with the explanations.

  • HTML not appearing in Emails

    - by John
    My website sends out html emails but most of my recipients are receiving them as HTML marked up source pages instead of the nice table layouts. The problem doesn't appear to be an email client issue since the emails display properly in web mail clients like gmail, yahoo, hotmail etc... They also display properly when viewed through outlook or thunderbird that are connected to gmail, yahoo, hotmail etc... However, I have one domain name that I registered with a shared hosting provider called 1and1.com. I tried viewing my emails through their webmail client, thunderbird and outlook, but in all three cases, only the html mark up showed up. Also, I assume most of my recipients use MS Outlook with MS Exchange Server because they are business/finance people. Unfortunately, I don't know how to get an email that's managed by an MS Exchange Server. I made sure I'm sending my emails with the following headers: MIME-Version: 1.0 Content-type: text/html; charset=iso-8859-1 Does anyone know what might be wrong? can anyone recommend a solution?

  • XMLHttpRequest POST Data Size

    - by usurper
    Hi, Is there a size limit to a XHR POST request? I am using the POST method for saving textdata into MySQL using PHP script and the data is cut off. Firebug sends me the following message: ... Firebug request size limit has been reached by Firebug. ... This is my code for sending the data: function makeXHR(recordData) { xmlhttp = createXHR(); var body = "q=" + encodeURIComponent(recordData); xmlhttp.open("POST", "insertRowData.php", true); xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.setRequestHeader("Content-length", body.length); xmlhttp.setRequestHeader("Connection", "close"); xmlhttp.onreadystatechange = function() { if(xmlhttp.readyState == 4 && xmlhttp.status == 200) { //alert(xmlhttp.responseText); alert("Records were saved successfully!"); } } xmlhttp.send(body); } The only solution I can think of is splitting the data and making a queue of XHR requests but I don't like it. Is there another way?

  • Thread loses Message after wait() and notify()

    - by fugu2.0
    Hey Guys! I have a problem handling messages in a Thread. My run-method looks like this public void run() { Looper.prepareLooper(); parserHandler = new Handler { public void handleMessage(Message msg) { Log.i("","id from message: "+msg.getData.getString("id")); // handle message this.wait(); } } } I have several Activities sending messages to this thread, like this: Message parserMessage = new Message(); Bundle data = new Bundle(); data.putString("id", realId); data.putString("callingClass", "CategoryList"); parserMessage.setData(data); parserMessage.what = PARSE_CATEGORIES_OR_PRODUCTS; parserHandler = parser.getParserHandler(); synchronized (parserHandler) { parserHandler.notify(); Log.i("","message ID: " + parserMessage.getData().getString("id")); } parserHandler.sendMessage(parserMessage); The problem is that the run-method logs "id from message: null" though "message ID" has a value in the Log-statement. Why does the message "lose" it's data when being send to the thread? Has it something to do with the notify? Thanks for your help

  • Forwarding HTTP Request with Direct Server Return

    - by Daniel Crabtree
    I have servers spread across several data centers, each storing different files. I want users to be able to access the files on all servers through a single domain and have the individual servers return the files directly to the users. The following shows a simple example: 1) The user's browser requests http://www.example.com/files/file1.zip 2) Request goes to server A, based on the DNS A record for example.com. 3) Server A analyzes the request and works out that /files/file1.zip is stored on server B. 4) Server A forwards the request to server B. 5) Server B returns file1.zip directly to the user without going through server A. Note: steps 4 and 5 must be transparent to the user and cannot involve sending a redirect to the user as that would violate the requirement of a single domain. From my research, what I want to achieve is called "Direct Server Return" and it is a common setup for load balancing. It is also sometimes called a half reverse proxy. For step 4, it sounds like I need to do MAC Address Translation and then pass the request back onto the network and for servers outside the network of server A tunneling will be required. For step 5, I simply need to configure server B, as per the real servers in a load balancing setup. Namely, server B should have server A's IP address on the loopback interface and it should not answer any ARP requests for that IP address. My problem is how to actually achieve step 4? I have found plenty of hardware and software that can do this for simple load balancing at layer 4, but these solutions fall short and cannot handle the kind of custom routing I require. It seems like I will need to roll my own solution. Ideally, I would like to do the routing / forwarding at the web server level, i.e. in PHP or C# / ASP.net. However, I am open to doing it at a lower level such as Apache or IIS, or at an even lower level, i.e. a custom proxy service in front of everything.

  • How to convert string with double high/wide characters to normal string [VC++6]

    - by Shaitan00
    My application typically recieves a string in the following format: " Item $5.69 " Some contants I always expect: - the LENGHT always 20 characters - the start index of the text always [5] - and most importantly the index of the DECIMAL for the price always [14] In order to identify this string correctly I validate all the expected contants listed above .... Some of my clients have now started sending the string with Doube-High / Double-Wide values (pair of characters which represent a single readable character) similar to the following: " Item $x80x90.x81x91x82x92 " For testing I simply scan the string character-by-character, compare char[i] and char[i+1] and replace these pairs with their corresponding single character when a match is found (works fine) as follows: [Code] for (int i=0; i < sData.length(); i++) { char ch = sData[i] & 0xFF; char ch2 = sData[i+1] & 0xFF; if (ch == '\x80' && ch2 == '\x90') zData.replace("\x80\x90", "0"); else if (ch == '\x81' && ch2 == '\x91') zData.replace("\x81\x91", "1"); else if (ch == '\x82' && ch2 == '\x92') zData.replace("\x82\x92", "2"); ... ... ... } [/Code] But the result is something like this: " Item $5.69 " Notice how this no longer matches my expectation: the lenght is now 17 (instead of 20) due to the 3 conversions and the decimal is now at index 13 (instead of 14) due to the conversion of the "5" before the decimal point. Ideally I would like to convert the string to a normal readable format keeping the constants (length, index of text, index of decimal) at the same place (so the rest of my application is re-usable) ... or any other suggestion (I'm pretty much stuck with this)... Is there a STANDARD way of dealing with these type of characters? Any help would be greatly appreciated, I've been stuck on this for a while now ... Thanks,

  • Which is the best way to encode batch videos on server side?

    - by albanx
    Hello I am making a general question since I am a developer and I have no advance experience on video elaboration. I have to preparare a web application with the purpose to allow video files upload on our company server and then video elaboration by server, on user command. The purpose of the web application is to allow to the user to make some elaboration on video depending on user action launch from the web app: (server has to ) convert video in different format(mp4, flv...) extact keyframes from video and saves them in jpeg format possibility to extract audio from video automatic control of quality audio & video (black frames,silences detection) change scene detection and keyframe extraction ..... This what's my bosses wanted from the web based application (with the server support obviously), and I understand only the first 3 points of this list, the rest for me was arabic.... My question is: Which is the best and fastest server side application for this works, that can support multiple batch video conversions, from command line (comand line for php-soap-socket interaction or something else..)? Is suitable Adobe Media Server for batch video conversion? Which are adobe products that can be used for this purpose? Note: I have experience with Indesign Server scripting programing (sending xml with php and soap call...), and I am looking to something similiar for video elaboration. I will appreciate any answers. THANKS ALL

  • Need help with threads in a client/server

    - by nunos
    For college, I am developing a local relay chat. I have to program a chat server and client that will only work on sending messages on different terminal windows on the same computer with threads and fifos. The fifos part I am having no trouble, the threads part is the one that is giving me some headaches. The server has one thread for receiving commands from a fifo (used by all clients) and another thread for each client that is connected. For each client that is connected I need to know a certain information. Firstly, I was using global variables, which worked as longs as there was only one client connected, which is much of a chat, to chat alone. So, ideally I would have some data like: -nickname -name -email -etc... per client that is connected. However, I don't know how to do that. I could create a client_data[MAX_NUMBER_OF_THREADS] where client_data was a struct with everything I needed to have access to, but this would require to, in every communication between server and client to ask for the id of the client in the array client_data and that does not seem very pratical I could also instantiate a client_data immediately after creating the thread but it would only be available in that block, and that is not very pratical either. As you can see I am in need of a little guidance here. Any comment, piece of code or link to any relevant information is greatly appreciated. Thanks.

  • Increment the number of times an article has been read

    - by r.sendecky
    I have a situation where I need to increase the number of time article has been read. Once someone opens an article it should be reflected in the database by incrementing number of reads by one. Simple. Sending POST request to the server increments the number of reads by one. The article in question is supplied via URL parameter. Doing it manually by typing the URL in a browser works as expected. So server side is not at fault. My problems start with the javascript side of it or rather jquery. I hook the event to the article link. So every time a user clicks on the article link it increments the number of reads like so: $('#list-articles .article-link').click(function(e){ var oid = $(this).parent().parent().attr('data-oid').toString(); //Get the article id $.post( "/articles/viewed/" + oid ); }); Now this does not work! Number is not increased. I don't prevent default action since I need the link to actually open and display the article. Now if I put an alert right after the post like this: $('#list-articles .article-link').click(function(e){ var oid = $(this).parent().parent().attr('data-oid').toString(); //Get the article id $.post( "/articles/viewed/" + oid ); alert(oid); }); This variant works. After I dismiss the alert window, the number is incremented. Why is this so?? How can I fix this to actually work without the alert event present?

  • The post->success->data variable is empty..

    - by Asaf
    Hello, I tried sending some data like so: <form action="http://www.someurl.com/something.php" id="login"> <input type="textbox" id="UserName" value="user"> <input type="textbox" id="Password" value="password"> <input type="submit" value="submit"> </form> <div id="result"></div> <script type="text/javascript"> $('form#login').submit(function() { $.post($('form#login').attr('action'), $('form#login').serialize(), function(data) { $('#result').html(data+'222') }); return false; }); </script> Now, the value of #result div change to 222... that is: the post was successful but for some reason there is no data, and when I go directly to something.php and post manually, it does bring back data (am I mistaken or does the post(success(data)) variable returns the whole page returned after you post something? if so, how could it be?)

  • Parameter meaning of CBasePin::GetMediaType(int iPosition, ...) method

    - by user325320
    Thanks to everyone who views my question. http://msdn.microsoft.com/en-us/library/windows/desktop/dd368709(v=vs.85).aspx It is not very clear from the documentation regarding the iPosition parameter for virtual HRESULT GetMediaType( int iPosition, CMediaType *pMediaType ); It is said "Zero-based index value.", but what kind of index it is? the index of the samples? I have a source filter sending the H.264 NALU flows (MEDIASUBTYPE_AVC1) and it works very well except that the SPS/PPS may be changed after the video is played for a while. The SPS and PPS are appended to the MPEG2VIDEOINFO structure, which is passed in CMediaType::SetFormat method when GetMediaType method is called. and there is another version of GetMediaType which accepts the iPosition parameter. It seems I can use this method to update the SPS / PPS. My question is: What does the iPosition param mean, and how does Decoder Filter know which SPS/PPS are assigned for each NALU sample. HRESULT GetMediaType(int iPosition, CMediaType *pMediaType) { ATLTRACE( "\nGetMediaType( iPosition = %d ) ", iPosition); CheckPointer(pMediaType,E_POINTER); CAutoLock lock(m_pFilter->pStateLock()); if (iPosition < 0) { return E_INVALIDARG; } if (iPosition == 0) { pMediaType->InitMediaType(); pMediaType->SetType(&MEDIATYPE_Video); pMediaType->SetFormatType(&FORMAT_MPEG2Video); pMediaType->SetSubtype(&MEDIASUBTYPE_AVC1); pMediaType->SetVariableSize(); } int nCurrentSampleID; DWORD dwSize = m_pFlvFile->GetVideoFormatBufferSize(nCurrentSampleID); LPBYTE pBuffer = pMediaType->ReallocFormatBuffer(dwSize); memcpy( pBuffer, m_pFlvFile->GetVideoFormatBuffer(nCurrentSampleID), dwSize); pMediaType->SetFormat(pBuffer, dwSize); return S_OK; }

  • Linq to SQL duplicating entry when referencing FK

    - by Oscar
    Hi! I am still facing some problems when using LINQ-to-SQL. I am also looking for answers by myself, but this problem is so akward that I am having problems to find the right keywords to look for it. I have this code here: public CustomTask SaveTask(string token, CustomTask task) { TrackingDataContext dataConext = new TrackingDataContext(); //Check the token for security if (SessionTokenBase.Instance.ExistsToken(Convert.ToInt32(token)) == null) return null; //Populates the Task - the "real" Linq to SQL object Task t = new Task(); t.Title = task.Title; t.Description = task.Description; //****The next 4 lines are important**** if (task.Severity != null) t.Severity = task.Severity; else t.SeverityID = task.SeverityID; t.StateID = task.StateID; if (task.TeamMember != null) t.TeamMember = task.TeamMember; else t.ReporterID = task.ReporterID; if (task.ReporterTeam != null) t.Team = task.ReporterTeam; else t.ReporterTeamID = task.ReporterTeamID; //Saves/Updates the task dataConext.Tasks.InsertOnSubmit(t); dataConext.SubmitChanges(); task.ID = t.ID; return task; } The problem is that I am sending the ID of the severity, and then, when I get this situation: DB State before calling the method: ID Name 1 high 2 medium 3 low Call the method selecting "medium" as severity DB State after calling the method: ID Name 1 high 2 medium 3 low 4 medium The point is: -It identified that the ID was related to the Medium entry (and for this reason it could populate the "Name" Column correctly), but if duplicated this entry. The problem is: Why?!! Some explanation about the code: CustomTask is almost the same as Task, but I was having problems regarding serialization as can be seen here I don't want to send the Severity property populated because I want my message to be as small as possible.

  • Java website protection solutions (especially XSS)

    - by Mark
    I'm developing a web application, and facing some security problems. In my app users can send messages and see other's (a bulletin board like app). I'm validating all the form fields that users can send to my app. There are some very easy fields, like "nick name", that can be 6-10 alpabetical characters, or message sending time, which is sended to the users as a string, and then (when users ask for messages, that are "younger" or "older" than a date) I parse this with SimpleDateFormat (I'm developing in java, but my question is not related to only java). The big problem is the message field. I can't restrict it to only alphabetical characters (upper or lowercase), because I have to deal with some often use characters like ",',/,{,} etc... (users would not be satisfied if the system didn't allow them to use these stuff) According to this http://ha.ckers.org/xss.html, there are a lot of ways people can "hack" my site. But I'm wondering, is there any way I can do to prevent that? Not all, because there is no 100% protection, but I'd like a solution that can protect my site. I'm using servlets on the server side, and jQuery, on the client side. My app is "full" AJAX, so users open 1 JSP, then all the data is downloaded and rendered by jQuery using JSON. (yeah, I know it's not "users-without-javascript" friendly, but it's 2010, right? :-) ) I know front end validation is not enough. I'd like to use 3 layer validation: - 1. front end, javascript validate the data, then send to the server - 2. server side, the same validation, if there is anything, that shouldn't be there (because of client side javascript), I BAN the user - 3. if there is anything that I wasn't able to catch earlier, the rendering process handle and render appropriately Is there any "out of the box" solution, especially for java? Or other solution that I can use?

  • Need Help with .NET OpenId HttpHandler

    - by Mark E
    I'm trying to use a single HTTPHandler to authenticate a user's open id and receive a claimresponse. The initial authentication works, but the claimresponse does not. The error I receive is "This webpage has a redirect loop." What am I doing wrong? public class OpenIdLogin : IHttpHandler { private HttpContext _context = null; public void ProcessRequest(HttpContext context) { _context = context; var openid = new OpenIdRelyingParty(); var response = openid.GetResponse(); if (response == null) { // Stage 2: user submitting Identifier openid.CreateRequest(context.Request.Form["openid_identifier"]).RedirectToProvider(); } else { // Stage 3: OpenID Provider sending assertion response switch (response.Status) { case AuthenticationStatus.Authenticated: //FormsAuthentication.RedirectFromLoginPage(response.ClaimedIdentifier, false); string identifier = response.ClaimedIdentifier; //****** TODO only proceed if we don't have the user's extended info in the database ************** ClaimsResponse claim = response.GetExtension<ClaimsResponse>(); if (claim == null) { //IAuthenticationRequest req = openid.CreateRequest(identifier); IAuthenticationRequest req = openid.CreateRequest(Identifier.Parse(identifier)); var fields = new ClaimsRequest(); fields.Email = DemandLevel.Request; req.AddExtension(fields); req.RedirectingResponse.Send(); //Is this correct? } else { context.Response.ContentType = "text/plain"; context.Response.Write(claim.Email); //claim.FullName; } break; case AuthenticationStatus.Canceled: //TODO break; case AuthenticationStatus.Failed: //TODO break; } } }

  • Celery / Django Single Tasks being run multiple times

    - by felix001
    I'm facing an issue where I'm placing a task into the queue and it is being run multiple times. From the celery logs I can see that the same worker is running the task ... [2014-06-06 15:12:20,731: INFO/MainProcess] Received task: input.tasks.add_queue [2014-06-06 15:12:20,750: INFO/Worker-2] starting runner..

Im using Django 1.6 with RabbitMQ. The method for placing into the queue is via placing a delay on a function. This function (task decorator is added( then calls a class which is run. Has anyone any idea on the best way to troubleshoot this ? Edit : As requested heres the code, views.py In my view im sending my data to the queue via ... from input.tasks import add_queue_project add_queue_project.delay(data) tasks.py from celery.decorators import task @task() def add_queue_project(data): """ run project """ logger = logging_setup(app="project") logger.info("starting project runner..") f = project_runner(data) f.main() class project_runner(): """ main project runner """ def __init__(self,data): self.data = data self.logger = logging_setup(app="project") def self.main(self): ....

  • Queueing method calls - any idea how?

    - by TomTom
    I write a heavily asynchronseous application. I am looking for a way to queue method calls, similar to what BeginInvoke / EndInvoke does.... but on my OWN queue. The reaqson is that I am having my own optimized message queueing system using a threadpool but at the same time making sure every component is single threaded in the requests (i.e. one thread only handles messages for a component). I Have a lot of messages going back and forth. For limited use, I would really love to be able to just queue a message call with parameters, instead of having to define my own parameter, method wrapping / unwrapping just for the sake of doing a lot of admnistrative calls. I also do not always want to bypass the queue, and I definitely do not want the sending service to wait for the other service to respond. Anyone knows of a way to intercept a method call? Some way to utilize TransparentProxy / Virtual Proxy for this? ;) ServicedComponent? I would like this to be as little overhead as possible ;)

  • If attacker has original data, and encrypted data, can they determine the passphrase?

    - by Brad Cupit
    If an attacker has several distinct items (for example: e-mail addresses) and knows the encrypted value of each item, can the attacker more easily determine the secret passphrase used to encrypt those items? Meaning, can they determine the passphrase without resorting to brute force? This question may sound strange, so let me provide a use-case: User signs up to a site with their e-mail address Server sends that e-mail address a confirmation URL (for example: https://my.app.com/confirmEmailAddress/bill%40yahoo.com) Attacker can guess the confirmation URL and therefore can sign up with someone else's e-mail address, and 'confirm' it without ever having to sign in to that person's e-mail account and see the confirmation URL. This is a problem. Instead of sending the e-mail address plain text in the URL, we'll send it encrypted by a secret passphrase. (I know the attacker could still intercept the e-mail sent by the server, since e-mail are plain text, but bear with me here.) If an attacker then signs up with multiple free e-mail accounts and sees multiple URLs, each with the corresponding encrypted e-mail address, could the attacker more easily determine the passphrase used for encryption? Alternative Solution I could instead send a random number or one-way hash of their e-mail address (plus random salt). This eliminates storing the secret passphrase, but it means I need to store that random number/hash in the database. The original approach above does not require this extra table. I'm leaning towards the the one-way hash + extra table solution, but I still would like to know the answer: does having multiple unencrypted e-mail addresses and their encrypted counterparts make it easier to determine the passphrase used?

  • Problems with Getting Remote Contents using Google App Engine

    - by dade
    Here is the client side code. It is running insdide a Google Gadgets var params = {}; params[gadgets.io.RequestParameters.CONTENT_TYPE] = gadgets.io.ContentType.JSON; var url = "http://invplatformtest.appspot.com/getrecent/"; gadgets.io.makeRequest(url, response, params); The response function is: function response(obj) { var r = obj.data; alert(r['name']); } while on the server end, the python code sending the JSON is: class GetRecent(webapp.RequestHandler): def get(self): self.response.out.write({'name':'geocities'}) #i know this is where the problem is so how do i encode json in GAE? which is just supposed to send back a Json encoded string but when i run this, the javascript throws the following error: r is null alert(r['name']); If i were recieving just TEXT contents and my server send TEXT everything works fine. I only get this problem when am trying to send JSON. Where exactly is the problem? Am i encoding the JSON the wrong way on AppEngine? I tried using the JSON library but it looks as if this is not supported. Where is the problem exactly? :(
