  • Is the usage of Isolated Storage in Silverlight 3 a security concern

    - by Prashant
    I am using Silverlight 3 on my website. I have a Login Page for role based authentication, that routes users with different privileges to different parts of the website. I want to use something analogous to the Session Variables available in standard ASP.Net applications. I intend to use Isolated Storage to achieve this. But I am skeptical about security in this option, as the Isolated Storage exists on the client side, and can be manipulated on client side. I am new to the Isolated Storage concept and don't know about the security options provided by it in terms of Encryption and server-side validation etc. If any of you have used it or are aware of the security provided in this case, could you please shed some light on the same. Thanks

  • Keep-alive for long-lived HTTP session (not persistent HTTP)

    - by stackoverflowuser2010
    At work, we have a client-server system where clients submit requests to a web server through HTTP. The server-side processing can sometimes take more than 60 seconds, which is the proxy timeout value set by our company's IT staff and cannot be changed. Is there a way to keep the HTTP connection alive for longer than 60 seconds (preferably for an arbitrarily long period of time), either by heartbeat messages from the server or the client? I know there are HTTP 1.1 persistent connections, but that is not what I want. Does HTTP have a keep-alive capability, or would this have to be done at the TCP level through some sort of socket option?

  • Oracle 9i Session Disconnections

    - by mlaverd
    [Cross-Posting from ServerFault] I am in a development environment, and our test Oracle 9i server has been misbehaving for a few days now. What happens is that we have our JDBC connections disconnecting after a few successful connections. We got this box set up by our IT department and handed over to. It is 'our problem', so options like 'ask you DBA' isn't going to help me. :( Our server is set up with 3 plain databases (one is the main dev db, the other is the 'experimental' dev db). We use the Oracle 10 ojdbc14.jar thin JDBC driver (because of some bug in the version 9 of the driver). We're using Hibernate to talk to the DB. The only thing that I can see that changed is that we now have more users connecting to the server. Instead of one developer, we now have 3. With the Hibernate connection pools, I'm thinking that maybe we're hitting some limit? Anyone has any idea what's going on? Here's the stack trace on the client: Caused by: org.hibernate.exception.GenericJDBCException: could not execute query at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:126) [hibernate3.jar:na] at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:114) [hibernate3.jar:na] at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66) [hibernate3.jar:na] at org.hibernate.loader.Loader.doList(Loader.java:2235) [hibernate3.jar:na] at org.hibernate.loader.Loader.listIgnoreQueryCache(Loader.java:2129) [hibernate3.jar:na] at org.hibernate.loader.Loader.list(Loader.java:2124) [hibernate3.jar:na] at org.hibernate.loader.hql.QueryLoader.list(QueryLoader.java:401) [hibernate3.jar:na] at org.hibernate.hql.ast.QueryTranslatorImpl.list(QueryTranslatorImpl.java:363) [hibernate3.jar:na] at org.hibernate.engine.query.HQLQueryPlan.performList(HQLQueryPlan.java:196) [hibernate3.jar:na] at org.hibernate.impl.SessionImpl.list(SessionImpl.java:1149) [hibernate3.jar:na] at org.hibernate.impl.QueryImpl.list(QueryImpl.java:102) [hibernate3.jar:na] ...

  • How to Maintain per-Client State in a WCF Service?

    - by tbischel
    I've created a WCF service in which I would like it to maintain state between calls from the client. I figured the easiest way to do this was to add this attribute to the service: [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)] since this is supposed to keep a separate service alive for each client over the life of the client proxy (or timeout in the extreme case). I also added a test function that tracks a list of user inputs, and spits out a concatenated string with all the inputs over the life of the service. When I run this in the test client generated by visual studio, I find that the list I was using to hold past data is reset with each call. Is there something else I need to do to maintain state per session?

  • MVC Design Question

    - by 104286623826380127552
    On a MVC 2 website what I want to do is get a list of products / CategoryId. From that list, create a list of distinct CategoryId's. Then randomly pick a categoryId from the second list and use it to get all the products for that categoryId. I then want to store that CategoryId so that I don't display those products on the next run. I don't need any code examples to start. What I'm wondering is that I think I would put this code in a class in my model (Dll) and store the list of displayed CategoryId's in session. Is this a good solution or should I go another way? Thank you for you help

  • Best practice for storing global data in PHP?

    - by user281434
    Hi I'm running a web application that allows a user to log in. The user can add/remove content to his/her 'library' which is displayed on a page called "library.php". Instead of querying the database for the contents of the users library everytime they load "library.php", I want to store it globally for PHP when the user logs in, so that the query is only run once. Is there a best practice for doing this? fx. storing their library in an array in a session? Thanks for your time

  • Getting session authenticity token via ajax (rails, jquery)

    - by ming yeow
    Hi folks, I wish to authenticate a user without having the page reloaded, and having the user submit a given form. However, the problem that I immediately run into here is that the authenticity token typically gets set when the page is reloaded. I need the authenticity token for the form submission, but i do not have it yet because the page is yet to reload. I figure this cannot be that rare - anyone has any idea on how to resolve this? 1 idea could be getting rails to pass back the authenticity token after authentication, but i do not know how to access it from the controller 1) not logined user sees form 2) not logined user types in message and submit 3) facebox asking for authentication 4) after authentication, submit form automatically without refreshing 5) //but authenticity token is needed for form submission, which is not there yet

  • CPU and profiling not supported for remote jvisualvm session

    - by yawn
    When monitoring a remote app (using jstatd) I can neither profile nor monitor cpu consumption. Heap monitoring (provided I do not use G1) works. jvisualvm provides the message "Not supported for this JVM." in the CPU graph window. Is there anything missing in my setup? The google showed up next to no results. The local environment (Mac OS X 10.6): java version "1.6.0_15" Java(TM) SE Runtime Environment (build 1.6.0_15-b03-219) Java HotSpot(TM) 64-Bit Server VM (build 14.1-b02-90, mixed mode) The remote environment (Linux version 2.6.16.27-0.9-smp (gcc version 4.1.0 (SUSE Linux))): java version "1.6.0_16" Java(TM) SE Runtime Environment (build 1.6.0_16-b01) Java HotSpot(TM) 64-Bit Server VM (build 14.2-b01, mixed mode) Local monitoring works as advertised.

  • What effects drawing charts/diagrams from $_SESSION data under php5, which worked under php4?

    - by ste_php
    Hello, I have a script generating 3 diagrams from $_SESSION variables which work fine under php4 with register_globals = off, but when I parse the same script as php5 I get no diagram. The diagrams a drawn from GD libary and it works, if I set the data into an Array (manually filled) within the script file. But I need a way to get it work on php5, without much changes. Are there any SESSION settings or php-settings which might interfere with my script. I already checked a lot of the php-settings (changing php.ini over and over again), but found nothing what brings me the diagrams back. Hopefully someone of you could kick me into the right direction. Any Ideas? Thanks a lot.

  • ajax-based login fails: IE6 and IE7 ajax calls delete session data (session_id however is kept)

    - by mateipavel
    This question comes after two days of testing and debugging, right after the shock I had seeing that none of the websites i build using ajax-based login work in IE<8 The most simplified scenario si this: 1. mypage.php : session_start(); $_SESSION['mytest'] = 'x'; <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"> </script> <script type="text/javascript"> function loadit() { $.post('http://www.mysite.com/myajax.php', {action: 'test'}, function(result){alert(result);}, 'html'); } </script> <a href="javascript:void(0);" onclick="loadit(); return false;">test link</a> 2. myajax.php session_start(); print_r($_SESSION); print session_id(); When I click the "test link", the ajax call is made and the result is alert()-ed: IE6: weird bullet-character (&bull;) IE7: Array( ) <session_id> IE8/FF (Expected behaviour): Array( [mytest] => 'x' ) <session_id> I would really appreciate some pointers regarding: 1. why this happens 2. how to fix it Thank you.

  • How to dump memcache contents to console in a telnet session

    - by morpheous
    I am having problems with memcached, and I need to find what is actually stored in the cache. I have telnet'ed into the daemon and am listening on the port, and can send the daemon commands via the CLI. I want to know if anyone is aware of a command I can use to dump the contents of the cache to the console. I know of commands like 'flush_all' and 'stats' but those are not quite sufficient for what I want to do.

  • Can't authenticate with different NTLM credentials in one session with java.net.URLConnection

    - by ndn
    When I access a HTTP server using the standard Java API (java.net.URLConnection), the credentials are "cached" after the first successful authentication, and subsequent calls to Authenticator.setDefault() have no effect. So, I need to restart the application in order to use different credentials. I don't observe this effect when Basic Authentication is used. But I need to use NTLM for the server I'm accessing, and the Jakarta Commons HttpClient isn't an alternative either because it doesn't support NTLMv2 (see http://oaklandsoftware.com/papers/ntlm.html) Looking at the packets using Wireshark, I also observe that before the first successful authentication, an authentication with the current Windows credentials is attempted first. But after succesful authentication, only the saved credentials are used. Is there any way to reset or change the credentials java.net.Authenticator is using after a successful NTLM authentication?

  • EJB3 Caching Instance Variables

    - by Justin
    Hi, I've noticed some strange code on a project I am working on - its a SLSB EJB3, and it uses a private instance variable to maintain a cache of data (it even calls it dataCache or something), with a getter/setter. For EJB2 and bellow, this was a typical EJB antipattern - SLSBs are not meant to retain state in between invocations, theres no guarantee you'll see the same data on a subsequent invocation. One of my colleagues said maybe its ok in EJB3 (we don't have much EJB3 experience), but still, its a Stateless Session Bean - why is it trying to maintain state, this doesn't make sense. Can anyone confirm if this is still a bad idea in EJB3 land, or if somehow it is ok? Thanks if you can help, Justin

  • Guessess of my session value conflicts

    - by SmartestVEGA
    I have a asp.net web form which will submit information to come as emails. Whenever user fill the form and click on submit button,the information user entered will be sent as email. This web form has 4 page. but the web form will not use all 4 page on all requests. if the user select a particular value in first page, the form will bypass the 3rd page and go the last 4th page(like...page1,2,4). IF it is any other values selected in the first page. form will navigate as page1,2,3,4. So now my problem is when multiple users access the same website, the value in the first page get combines from different users and the form will act abnormally.Sometime it will bypass sometimes it will not bypass the page3 Show below is the variable decalrations: Public strRoleType As String = String.Empty Protected Shared isAreaSelected As Integer = 0 Protected Shared isStoreSelected As Integer = 0 Protected Shared isHeadOfficeSelected As Integer = 0 Protected Shared isRegionSelected As Integer = 0 I guess the problem is with strRoleType variable whether it is getting values from different users. Do any have any work around?

  • Is it possible to attach a debugging session to a running program in eclipse CDT

    - by stu
    I'm writing a netscape iplanet plugin (on solaris/C using eclipse) which is basically a shared object with specific entry points, and I'd like to be able to debug the shared object with eclipse's debugger (gdb). I remember doing something similar in AIX where you could make xldb attach to a running process. Is it possible to get eclipse to run gdb to attach to a running binary? And should I expect grief because I want to debug a dynamically loaded piece of code?

  • .NET TCP socket with session

    - by Zé Carlos
    Is there any way of dealing with sessions with sockets in C#? Example of my problem: I have a server with a socket listening on port 5672. TcpListener socket = new TcpListener(localAddr, 5672); socket.Start(); Console.Write("Waiting for a connection... "); // Perform a blocking call to accept requests. TcpClient client = socket.AcceptTcpClient(); Console.WriteLine("Connected to client!"); And i have two clients that will send one byte. Client A send 0x1 and client B send 0x2. From the server side, i read this data like this: Byte[] bytes = new Byte[256]; String data = null; NetworkStream stream = client.GetStream(); while ((stream.Read(bytes, 0, bytes.Length)) != 0) { byte[] answer = new ... stream.Write(answer , 0, answer.Length); } Then client A sends 0x11. I need a way to know that this client is the same that sent "0x1" before.

  • Paging doesn't work in the Joomla Article Manager in the admin section

    - by SkippyFire
    I inherited a Joomla site that is having a problem with the article manager in the admin section. The pagination doesn't work! If I click the page number, forward, back, or page size, nothing happens! So I found out that someone had previously installed the iJoomla SEO plugin, but it never worked so they removed it. I think it is incompatible with the version I have. I setup a local environment with almost the same setup (I have 5.2.11 vs the servers 5.2.13) with Wamp Server, and I found that some of the session variables are missing! When dumped via print_r(), the $_SESSION variable is missing the "com_content", "global", and "com_plugins" arrays! So I guess that is the reason that paging doesn't work, because the "com_content" array looks like it has paging info in it. (maybe I'm wrong) So I'm running Version 1.5.13 on PHP Version 5.2.13 Anyone know why this would happen? Thanks in advance!

  • How to share sessions between PHP and ASP.net application?

    - by citronas
    My company took some old php application over. Due to our preference to ASP.net and to the lack of any documentation from the previous developer, we do not want to spend much resources on developing in PHP. For implementing new features, we will create an Asp.net application that has the same look to the user. We want to develop a kind of 'coexisting' web application. Therefore we must share sessions between an PHP and an Asp.net webapplication project, because there is a usermanagement involved with an existing MySQL database. (e.g. link 'A' directs to the PHP website, and link 'B' directs to the asp.net application) How can we share the session between and PHP and an asp.net application? And does anyone have a hint for this 'coexisting' thing, that might be useful in development? Edit: IIS 6 would be our targeted server, altough IIS 7.5 would also be an option

  • C# System.IO.FileInfo gets virtual address which has sessions key

    Okay so the following line returns null because its path cannot be found: System.IO.FileInfo fi = di.GetFiles()[position]; What I am currently doing is: <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <ctl:Gallery runat="server" ID="Gallery1" FolderUrl="~/images/1/" Size="100" /> When this is invoked System.IO.FileInfo fi = di.GetFiles()[position]; it has the value similar to this: C:\Users\SomeUsername\Desktop\Tiamo\(S(mr1h0l55ycuixfbtqxbmttek))\images\1 Any idea how I can return the virtual path without actually having the session key in there? Thank you in advanced for any help you may give :) much appreciated.
