View 7 RepliesI am using Httphandler to access my pages. Have Loginstatus Control on the master pages.
OnLoggingOut for the Loginstatus control I am doing a Session.abandon()... But My session_end
does not get called in the Gobal.asax.I tried link button and everything. but when I take out the httphandler the Session_end gets executed in global.asax
I can handle the full session end on my own but is there any way to call Session_end in global.asax?

View 3 RepliesI'm trying to secure my web application so XML files it contains can't be downloaded. I thought it would be as simple as adding these to the "httpHandlers" section of web.config:
<remove verb="*" path="*.xml"/>
<add verb="*" path="*.xml" type="System.Web.HttpForbiddenHandler"/>
This failed - the XML files could still be downloaded easily. I tried different browsers in case they were caching, but everything could download the XML files without any trouble. I thought this might be due to some special handling of XML, so I tried mocking up an alternative based on ".txt123" files. I added this file with some dummy content:

We have a handler to deal with .dat files.. everything is already setup and server is acknowledging the file type and doing its thing to handle it..
But the handler requires 1 bit of information along with the HTTP request which is a physical file path.. the file name it knows based on the file we call , but how can i pass a custom header along with the request so that the handler will use that when the request is made?
Basically when on our player.aspx page, i will have a button, when you click that button a request is made to the .dat file, but along with that request i need to send the physical file path.. how can i do that?
I have this HttpHandler which works great ONLY for PDF files:
=================================================================
public void ProcessRequest(HttpContext context)
{
HttpResponse response = HttpContext.Current.Response;

I need to access image files (.jpg) on a server other than the web server my app runs on. I would like to use an httphandler to do this but I am unsure of the syntax to specify the path. I have tried mapping a drive on the web server to the file server but that didn't work. I have tried using a UNC path but that did not work either.

I am using uploadify for a photography site I am building. I have an HTTPHandler that I'm using to save the posted file. What I am wondering is if I can resize images, insert a record of the image into a db and save the image from the HTTPHandler? This is my first experience with HTTPHandlers so forgive me if there is an obivious answer for this.
View 1 RepliesI have a problem with large respones and IIS7, the server runs out of memory. I've written the test code below that works pretty much like my real code... When i start to download the file i can se the memory usage rise until it hits 100% and Firefox complaints about lost connection to server, looks like IIS7 does not release cache or something.. Works in IIS6 by the way

I've tried to implement two different solutions that use either and HttpModule or and HttpHandler to do URLRewriting for me. These work great on IIS 7 within my local development environment in Integrated and Classic modes. Currently the production server is running IIS 6.0 on a shared hosting environment. It appears that the request at least hits both the Module and Handler as the URL above redirect to the particular friendly url, but it doesn't redirect and hit hte Module or Handler again. Instead I get a 404 error for the friendly URL.
View 2 RepliesSo I've read quite a few posts about how to do this, and it's still getting me. I'm trying to control access to a directory, but I continue to get a null session error. I'm doing my check in PostAcquireRequestState
[Code]....no matter where I put this, my session always comes back null. I am using IRequireSessionState on the class as well. Am I pulling the context wrong?
I have IReadOnlySessionState and IRequiresSessionState on my module but still httpApplication.Context.Session == null is this because these session state hasn't been created yet? is there a way around this?
View 2 Replieswhat should i write in web config file in asp.net so that my session time is extended. the exact location where should i place the code in web config
View 6 RepliesIn my website, the session is expired after 5 minutes. I need to extend the seesion state to minimum 4 hours. Currently, in web.config file I used the following code.
<sessionstate cookieless="false" timeout="1440"></sessionstate>
But its expired after just 5 minutes.
I hope I am posting into the right area... I want to know if you can access a session variable from a HTTP Module in IIS 7. Here is the scenario, I want to access the session values (i.e. User Object) from a HTTP Module. I have read oodles and tried many things but to no avail. I guess the application uses Forms authentication to authorize a logon to the site. I want to monitor the url that is submitted... RAWUrl property and if they are going to a certain page I want to grab their user object from THEIR session and validate them for access to that page. I want to use a httpmodule for this. The long and short of this is "Can I get access to session variables from the request from the httpmodule code behind? If I can, could you beso kind as to show me a working sample... I have tried many permutations on this using httpapplication, context and so forth and I can't seem to get access to session variables that would belong to the users request. it this possible?
View 1 RepliesI have read in many places that referencing IRequiresSessionState or IReadOnlySessionState will allow me access to the Session scoped variables from within the ProcessRequest method in an ASHX file.
I have implemented these changes, as follows, and I am unable to retrieve this data still, as the server returns a null object reference error:
using System;
using System.Web;
using System.Web.SessionState;[code]....
The error is most certainly specific to pulling data from the session, yet I am 100% certain that the session contains data in this key.
It shouldnt matter where I am storing the data (cookies, vs db, etc), right?
i am trying to pass a value, from my .aspx form to a ashx request via a session or a cookie,
the cookie exists but in the ashx it returns a null, and same with the session value.
I have a module that subscribes to PreRequestHandlerExecute event, which uses the Session object. When i set the webconfig compilationdebug flag to false, the Session object is null when making requests to the web service. It works fine for .aspx requests, but only have problems for .asmx. When i set the debug flag to true everything works fine. I need to set this flag to false for production, but can't seem to get it work.I'm using II7 and the integrated pipeline, so this event will fire for all requests.
View 1 RepliesAfter adding a custom module, Module list is showing MyModule "Entry Type" as "Local".
and Entry Type of all other modules is "Inherited".
what is Entry Type and difference between "Local" and "Inherited"?
is httpmodules executed each and every time in request and response cycle ?? if Yes is it possible to disable a specific http module ??
View 3 RepliesWe have the timeout value set to 120 in our <form> tag within the web.config. We do not have a session timeout set.. and we have various connection strings.
We are having a problem where a session variable will disappear (become NULL) .. but, the form evidently remains 'open'.. or no re-login is required..... so, my question(s):
1. what is the relationship between form timeout and session timeout
2. how do I set session timeout
I wanna write a method to get or set session timeout at run time.
