• Limiting the maximum number of concurrent requests django/apache

  - by Johan

  Hi, I have a django site that demonstrates the usage of a tool. One of my views takes a file as input and runs some fairly heavy computation trough an external python script and returns some output to the user. The tool runs fast enough to return the output in the same request though. I would however want to limit how many concurrent requests to this URL/view to keep the server from getting congested. Any tips on how i would go about doing this? The page in itself is very simple and the usage will be low.

• How can I make a security token automatically expire in a passive STS setup?

  - by Rising Star

  I have a passive STS set up for a new application I'm working on. I've noticed that when a user's session expires, the user is still authenticated. I would have thought that when the session expires, the user would no longer be authenticated. My boss discussed this with me as I am currently charged with setting up the authentication. He says that it would be good if we could make the user's log on expire after a certain period of inactivity similar to how the session expires. I am familiar with how to sign a user out with a few lines of code. How can I make it so that the user is automatically signed out after a specified period of inactivity? Currently, I have some code in the global.asax file that programmatically checks when the last request was and compares it to the current time; it then signs the user out if a certain period of time has expired.

• What is cached on a client machine when using https.

  - by TroyP

  I have an application that is working on https for everybody and on http for all but two users. The two users get a JavaScript error when trying to "edit" a page while on http but can edit the page on https. The problem is for occurs for both IE6 and FF3.6 for one of these users. Others have no problem using any browser. I have used Charles Proxy to look at the server response and no request is being made to https when on http and all browser requests return successfully. I have cleared all caches known to me on the clients (browser, jvm). Are http and https caches stored in different locations on the clients computers. Could a cached encrypted file be being read on the unencrypted port.

• ASP.NET cached aspx page & IIS logs

  - by Vishal Seth

  Hi guys, Is there any way to find out if ASP.Net runtime has served a cached copy of ASPX page or actually went through the page life cycle? Here is my problem: I'm seeing many entries in my IIS log files that were served successfully (200 OK). I've a corresponding logging code (Log4Net API) in the Session_Start and Application_BeginRequest() events that is logging every request to my DB with more details. I'm not seeing any corresponding entries in my SQL DB for some cases that should have been created by Log4Net code. Are there any logs available to find out if a cached copy was served by .NET worker process? Moreover, if my logging code would throw an exception, won't that show up as 500 in IIS logs? The code is on Windows 2008 Server, IIS 7.

• Map the physical file path in asp.net mvc

  - by rmassart

  Hi, I am trying to read an XSLT file from disk in my ASP.Net MVC controller. What I am doing is the following: string filepath = HttpContext.Request.PhysicalApplicationPath; filepath += "/Content/Xsl/pubmed.xslt"; string xsl = System.IO.File.ReadAllText(filepath); However, half way down this thread on forums.asp.net there is the following quote HttpContext.Current is evil and if you use it anywhere in your mvc app you are doing something wrong because you do not need it. Whilst I am not using "Current", I am wondering what is the best way to determine the absolute physical path of a file in MVC? For some reason (I don't know why!) HttpContext doesn't feel right for me. Is there a better (or recommended/best practice) way of reading files from disk in ASP.Net MVC? Thanks for your help, Robin

• PHP File Serving Script: Unreliable Downloads?

  - by JGB146

  This post started as a question on ServerFault ( http://serverfault.com/questions/131156/user-receiving-partial-downloads ) but I determined that our php script was the culprit. So I'm issuing an updated question here about what I believe is the actual issue. I am using a php script to verify permissions and then serve up a file for users of my website to download. Most of the time, this works, but recently one user has been seeing problems with larger downloads. He is only getting ~80% of downloads for files that are 100MB in size. Also, all downloads from this script fail to report a filesize. Further, tests revealed that the same user COULD reliably download each of the failed files if given a direct link (at which point the filesize is reported). Here's the relevant snippet of code that we are using to serve the file: header("Content-type:$contenttype"); $len = filesize($filename); header("Content-Length: $len"); header("Content-Disposition: attachment; filename=".$title.".".$ext); readfile($filename); Note that $contenttype, $filename, $title, and $ext are all set correctly before we get here. These have been triple-checked. None of them are the problem. Also, $len does provide the correct filesize. While researching this issue, I came across this post: http://stackoverflow.com/questions/1334471/content-length-header-always-zero It seems that I am encountering the same issue. When I use the script, I get chunked encoding on the file and no size is set for content-length. I'm hypothesizing that something is going wrong on the large downloads, leading him to get a zero-length chunk before the end of the file. Here's what the headers look like for a direct request: http://www.grinderschool.com/videos/zfff5061b65ae00e8b21/KillsAids021.wmv GET /videos/zfff5061b65ae00e8b21/KillsAids021.wmv HTTP/1.1 Host: www.grinderschool.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 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 Referer: http://www.grinderschool.com/phpBB3/viewtopic.php?f=14&p=29468 Cookie: style_cookie=printonly; phpbb3_7c544_u=2; phpbb3_7c544_k=44b832912e5f887d; phpbb3_7c544_sid=e8852df42e08cc1b2250300c2897f78f; __utma=174624884.2719561324781918700.1251850714.1270986325.1270989003.575; __utmz=174624884.1264524375.411.12.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=low%20stakes%20poker%20videos; phpbb3_cmviy_k=; phpbb3_cmviy_u=2; phpbb3_cmviy_sid=d8df5c0943863004ca40ef9c392d371d; __utmb=174624884.4.10.1270989003; __utmc=174624884 Pragma: no-cache Cache-Control: no-cache HTTP/1.1 200 OK Date: Sun, 11 Apr 2010 12:57:41 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 mod_auth_passthrough/2.1 FrontPage/5.0.2.2635 Last-Modified: Sun, 04 Apr 2010 12:51:06 GMT Etag: "eb42d6-7d9b843-48368aa6dc280" Accept-Ranges: bytes Content-Length: 131708995 Keep-Alive: timeout=10, max=30 Connection: Keep-Alive Content-Type: video/x-ms-wmv And here's what they look like for the request answered by my script: http://www.grinderschool.com/download_video_test.php?t=KillsAids021&format=wmv GET /download_video_test.php?t=KillsAids021&format=wmv HTTP/1.1 Host: www.grinderschool.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 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 Cookie: style_cookie=printonly; phpbb3_7c544_u=2; phpbb3_7c544_k=44b832912e5f887d; phpbb3_7c544_sid=e8852df42e08cc1b2250300c2897f78f; __utma=174624884.2719561324781918700.1251850714.1270986325.1270989003.575; __utmz=174624884.1264524375.411.12.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=low%20stakes%20poker%20videos; phpbb3_cmviy_k=; phpbb3_cmviy_u=2; phpbb3_cmviy_sid=d8df5c0943863004ca40ef9c392d371d; __utmb=174624884.4.10.1270989003; __utmc=174624884 HTTP/1.1 200 OK Date: Sun, 11 Apr 2010 12:58:02 GMT Server: Apache/2.2.14 (Unix) mod_ssl/2.2.14 OpenSSL/0.9.8l DAV/2 mod_auth_passthrough/2.1 FrontPage/5.0.2.2635 X-Powered-By: PHP/5.2.11 Content-Disposition: attachment; filename=KillsAids021.wmv Vary: Accept-Encoding Content-Encoding: gzip Keep-Alive: timeout=10, max=30 Connection: Keep-Alive Transfer-Encoding: chunked Content-Type: video/x-ms-wmv So the question is...what can I do to make downloads from the script work properly?

• Problem with ajax and posting non-latin characters

  - by jason

  Posting non-latin based languages with ajax + jquery doesn't save to mysql the correct text. What I have done is this: I am getting multiple translated words from Google's translation api. The ajax request is showing the correct translations for all languages. But when i try and insert this into the db it shows up in php my admin as garbled text I added AddDefaultCharset UTF-8 to .htaccess file on the root. I tried setting the header in php to utf-8 and this did not work. I have tried adding a contentType to ajax setup but this didn't work also. Any suggestions appreciated. jason

• .NET MVC - Storing database result during single page result?

  - by ropstah

  Fairly simple issue which is solved in PHP by using a static variable. private static $pages; public function Pages() { if($pages == null) { $pages = new PageCollection(); $pages->findAll(); } } Everywhere in my code I use Pages()::someFindFunction() to make sure the results are fetched only once, and I use that same collection. I want the same in my .NET MVC application: use something like: <%=MySite.Pages.findById(1).Title%> In the code below, if I use a private variable, or if I use a public class with shared variables (doesn't matter) they are both persisted during the entire application. I want them to load the same way PHP does, once per request. Now where do I store the .NET equivalent of private static $pages, so that the code below works? //what to do with $pages?? Public Module MySite Public Function Pages() As PageCollection If $pages Is Nothing Then $pages.loadAll() End If Return $pages End Function End Module

• Prevent query string manipulation by adding a hash?

  - by saille

  To protect a web application from query string manipulation, I was considering adding a query string parameter to every url which stores a SHA1 hash of all the other query string parameters & values, then validating against the hash on every request. Does this method provide strong protection against user manipulation of query string values? Are there any other downsides/side-effects to doing this? I am not particularly concerned about the 'ugly' urls for this private web application. Url's will still be 'bookmarkable' as the hash will always be the same for the same query string arguments. This is an ASP.NET application.

  - by MKS

  Hi Guys, I am using C#. I am having below code in C#: protected override void OnInit(EventArgs e) { try { if (Session["boolSignOn"].ToString() == "true".ToString()) { lblPanelOpen.Text = Session["panelOpen"].ToString(); } else { lblPanelOpen.Text = Session["panelOpen"].ToString(); } } catch (Exception ex) { Logger.Error("Error processing request:" + ex.Message); } } protected override void OnLoad(EventArgs e) { try { if (!string.IsNullOrEmpty(Session["panelOpen"].ToString())) { lblPanelOpen.Text = string.Empty; Session.Remove("panelOpen"); } } catch (Exception ex) { Logger.Error("Unable to remove the session variable:" + ex.Message); } } In above code I am having a Session["panelOpen"] variable which is created from another user control and once my page is trying to render, I am storing Session["panelOpen"] in my hidden lblPanelOpen.Text on page OnInit() method, however when page is loaded completely then I am trying to remove the session variable. Please suggest!

• how do I assign a variable to a returned response in jQuery

  - by netrox

  I wanted to assign a returned value (just text) to a variable in jQuery. I wrote this: var hm=22; $.ajax({ type: "GET", url: "ajax_check_match.php", dataType: "text", success:callback }); function callback(data, status) { // assign ajaxed value to cm variable cm=data; if (hm != cm) { dosomething(); } } But it fails every time. Why is that the cm variable keeps getting undefined when it sends request. I set the php file to return 1 and it still says undefined. I opened ajax_check_match.php in browser and I see "1". I didn't see the point of using XML or JSON since a simple number would suffice. Or do I have to use XML/JSON?

• System.ServiceModel.CommunicationException on overloading webservice

  - by soldieraman

  I am load testing my webservice and get a System.ServiceModel.CommunicationException when I use 10 threads to communicate to it (without any sleep in between) - basically testing 10 conenctions at a time - through a windows application An error occurred while receiving the HTTP response to http://localhost/XXX/XXXService.asmx. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details. Why would this happen and how to best resolve it

• Real-time data on webpage with Django and jQuery

  - by Steven Hepting

  I would like a webpage that constantly updates a graph with new data as it arrives. Regularly, all the data you have is passed to a Django view at the beginning of the request. However, I need the page to be able to update itself with fresh information every few seconds to redraw the graph. Background The webpage will be similar to this http://www.panic.com/blog/2010/03/the-panic-status-board/. The data coming in will temperature values to be graphed measured by an Arduino and saved to the Django database (I've already done this part).

• How do I authenticate a Twitter user and access the API without leaving my iPhone app?

  - by thebossman

  I'd like to allow users to send out Tweets from my iPhone app. That's all the functionality I need at the moment. From what I know of the Twitter API, there's a standard authentication mechanism, which allows the developer to include the user's name and password in the request string that the application sends to Twitter. This method will no longer be supported come June 30, 2010. Given the timeframe, the better other choice is oAuth. One of the caveats of oAuth is that it requires a UIWebView to pop up within the app to allow the user to enter his or her credentials or a PIN number. None of the Twitter apps on my phone do this, however: Tweetie, TweetDeck and Twitterific. I assume they're using the first authentication method, but it seems like Twitter wouldn't deprecate an API that would hurt the user experience across the board. There must be an alternative method--what am I missing?

• how to avoid 'out of memory' errors when programmatically generating a lot of nodes in drupal?

  - by sprugman

  I'm creating about 150 nodes programmatically and running into 'out of memory' errors when doing it all in a single request. (I have a menu callback that generates the nodes and calls node_save() on them.) Example: for($i=0; $i<150; $i++) { $node = new stdClass(); $node->title="Foo $i"; $node->field_myfield[0]['value'] = "Bar $i"; ... node_save($node); } I've heard of BatchAPI, but never used it. Is that the right tool to get around this? The docs talk about timeouts, but not memory issues. Is there something simpler that I might be missing?

• Modify Emdeded String in C# compiled exe

  - by nitefrog

  I have an issue where I need to be able to have a compiled exe ( .net 3.5 c# ) that I will make copies of to distribute that will need to change a key for example before the exe is sent out. I cannot compile each time a new exe is needed. This is a thin client that will be used as part of a registration process. Is it possible to add a entry to a resource file with a blank value then when a request comes in have another application grab the blank default thin client, copy it, populate the blank value with the data needed. If yes how? If no do you have any ideas? I have been scratching my head for a few days now and the limitation as due to the boundaries I am required to work in. The other idea I has was to inject the value into a method, which I have no idea how I would even attempt that. Thanks.

• iPhone Setting ViewController nested in NSMutableArray

  Hello I'm trying to set attributes for a viewcontroller nested inside a NSMutableArray, for example I have 3 ViewController inside this array: FirstViewController *firstViewController = [FirstViewController alloc]; SecondViewController *secondViewController = [SecondViewController alloc]; ThirdViewController *thirdViewController = [ThirdViewController alloc]; NSMutableArray *viewControllerClasses = [[NSMutableArray alloc] initWithObjects: firstViewController, secondViewController, thirdViewController, nil]; for (int x=0; x<[viewControllerClasses count]; x++) { // as an example to set managedObjectContext I otherwise would set firstViewController.managedObjectContext = context; [viewControllerClasses objectAtIndex:x].managedObjectContext = context; } But this results in an error: Request for member "managedObjectContext" in something not a structure or union. Shouldn't be "firstViewController" be the same as [viewControllerClasses objectAtIndex:0]?

• Security when using GWT RPC

  - by gerdemb

  I have an POJO in Google Web Toolkit like this that I can retrieve from the server. class Person implements Serializable { String name; Date creationDate; } When the client makes changes, I save it back to the server using the GWT RemoteServiceServlet like this: rpcService.saveObject(myPerson,...) The problem is that the user shouldn't be able to change the creationDate. Since the RPC method is really just a HTTP POST to the server, it would be possible to modify the creationDate by changing the POST request. A simple solution would be to create a series of RPC functions like changeName(String newName), etc., but with a class with many fields would require many methods for each field, and would be inefficient to change many fields at once. I like the simplicity of having a single POJO that I can use on both the server and GWT client, but need a way to do it securely. Any ideas?
