According to MSDN documentation, this is supposed to set the Cache header "Expires" to a certian value. A check of fiddler for the response from my handler indicates the Expires is being ignored. Is this a known bug? I see other posts where people have just given up with out an answer.
View 2 RepliesI have a 3.5 app with a subfolder containing numerous documents. I want to control access to all files in this subfolder via an ASHX handler. My file system looks like this:
/Default.aspx
/web.config
/Filecabinet/Filecabinet.ashx
/Filecabinet/web.config
The content of the web.config in the files folder is simple:
[Code]....
This works fine on my WinXP / IIS6 developement box, but doesn't work at all when I upload it to my IIS7 / shared hosting account (GoDaddy). I know it doesn't work because I can access every file in the subfolder - the restrictions I wrote in my ASHX code-behind aren't taking affect at all.
as subject, how can i read Response Headers inside an httpmodule?
i need the "Content-encoding" header value.
I have an httpmodule and it has a handler for OnEndRequest. I am trying to write the HttpContext.Response.OutputStream to a file. I am trying to use the Read method of it. But when it is called the exception message i get is "Specified method is not supported". So i am not able to do what i want that is, write the response to a file on the disk. I am able to write the HttpContext.Request.InputStream to a file using its Read method which i do in a handler for OnBeginRequest.
View 2 Repliesi am trying to have a download on my page. I have implemented the code below but code execution stops after the download message pops up, even if i press save or cancel, nothing happens after that.
[Code]....
I have tried it a few times without Response.Clear() and Response.End() but it didn't make any difference to take these off. Is there anyway I can achieve this without having to using an IFrame?
I have written simple HttpModule. context.Response.Output.Write is working fine. but not context.Response.Write().

View 1 Repliesi manage the doc extension through a customized HttpHandler :
I set <add verb="GET" path="*/*.doc" type="MOMA.IWT.Framework.Portal.Components.HttpHandler.ResourcesHandler, PortalComponents" /> in the httpHandlers section of the web.config file and in IIS property i add a mapping for .doc with C:WINDOWSMicrosoft.NETFrameworkv2.0.50727aspnet_isapi.dll
So, when i try to get a file named like pippo.doc within my web application [URL) my handler intercept the request, all right but when i try to get [URL]the result is 400 bad request My question are: why the handler doesn't intercept the request? How can I open the pippo..doc document?
I've been trying to get image caching working for the last 8 hours and I keep the same problem time and time again, I'm trying to cache Images at the moment and then when thats succesful, apply this to cache my js and css files. I have at the moment Sql Dependancy caching working on my dynamic pages but the page still takes to long due to images not caching.
What I have tried is going to IIS7 Management and adding HTTP Response Header for the images folder and setting various things for the cache control.i dont care how long it caches it on the client or on the proxy servers i just would like it to check when the file was modified and compare it with the one in the client or proxy cache and if they are different then fetch the new image which has been ftp up. i could solve this by changing the image name but the thing is the image name is generated when they are ftp'd to the site by an application and the name is a direct reference to the product so i cant change the name each time, as it would mean making a lot of otherpages accross the board.
so What i would like, is to set and expiry date of lets say 32 days or more on the images and then check to see if they have changed by date modified or some other way of checking(Etags maybe) I'm not sure, if they have changed on the server then redownload and recache them, I tried using post-check and pre-check together but that just permantly cached them, so when i change the image the only way it would display the new image is to just hit F5.
In Brief, how can i Cache images, on the client machine/ proxy cache and recache them when the modified date of the file has changed.
am trying to write an HttpModule that will work in IIS7 with integrated pipeline mode AppPool. Within this module I need to access Session variables and to be able to capture the Session Start and End events. I have found a couple of articles on this topic that indicate the need to modify the behavior of the HttpHandler in PostAcquireRequestState to force the Session for the context to be initialized. The article I am using as a template is posted here:[URL]In my case I am getting the following error:
[NullReferenceException: Object reference not set to an instance of an object.] System.Web.PipelineModuleStepContainer.GetEventCount(RequestNotification notification, Boolean isPostEvent) +30 System.Web.PipelineStepManager.ResumeSteps(Exception error) +1112
System.Web.HttpApplication.BeginProcessRequestNotification(HttpContext context, AsyncCallback cb) +113 System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +616
I believe that this error implies a problem with attempting to attach an event handler multiple times. I am aware that the modules Init function can be called more than once and have set a static initialization flag which ensures that I will only ever attach the event handler once.In the most condensed form my code is as follows:
public class HttpModule : IHttpModule, IRequiresSessionState
After 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 ??
