I've seen a few posts about Application_BeginRequest, but non seems to have my problem.
My Application_BeginRequest is being called for every image in my website.
The StaticFile Handler is enabled with * as the Path, but it's at the end of the list.
Is this the normal behaviour? Or should I add .gif, .jpg and so on on top of the list?
This is on my IIS7.5 Win7 Development Server. Didn't check it on the production server yet.
Update:
Setting runAllManagedModulesForAllRequests=false would help. But then the ASP.NET URL Mapping does not work anymore. I tried disable it just for the image directly, but that had no effect?
I have two versions of a website. One runs on IIS server on a local PC, the other runs on the ASP.NET development environment included on Visual Studio (localhost). Apart from that, the file stucture of both is the same, although only the one running on IIS works properly, and this seems to be related to the fact that the IIS version calls Application_BeginRequest() where the other doesn't.
I've looked at the differences between IIS server and the ASP development environment in: [URL], and it says that IIS and the ASP development server deal with static content in that for IIS in that on IIS static content does not go through the ASP.NET runtime like it does on the dev environment (but I'm not sure exactly what this means).
I've done a number of tests involving images, etc, and have noticed that when the image is of the form:
<img src="Image/MyImage.jpg...>
the IIS server version calls Application_BeginRequest(), but the visual studio development environment version doesn't.
In my case, it is necessary to call Application_BeginRequest because this creates a new path and calls RewritePath().
The problem occurs when using links such as <a href="..." ...>, because if I use static content it won't call Application_BeginRequest() and the path won't be re-written. But If I change it to href=" %=ResolveUrl("~/...")%>" (for some reason, it will only call BeginRequest() if the path begins with a tilde ~), the path is re-written incorrectly.
I'm not really sure how to find out why the IIS version is calling Application_BeginRequest() from all the time (the callstack just says "external code"), or why it is calling it whereas the local dev server version isn't.
If anybody can explain this, or knows of any sites that go into this so I can master the basics, I'd be very grateful.
I have a site with multiple domains pointing to it. I wanted to redirect all requests to main domain so I've created a method called RedirectToRealDomain("domain.com") to check and redirect all requests to my preferred domainAt the moment it lives on Session_Start but I am planing to move it to Application_BeginRequest event. As I understand Session_Start only raised when new session started but Application_BeginRequest raised on all requests. RedirectToRealDomain method doesn't do any DB lookups or anything expensive apart from comparing strings.
I've got some tracing statements with timestamps on an ASP.Net IIS application that gets a lot of traffic. I've got trace statements at the end of Application_BeginRequest and the beginning of Application_PreRequestHandlerExecute in my Global.asax. Occasionally there is a big delay between the end of BeginRequest and the start of PreRequestHandlerExecute, i.e. more than 5 seconds.
What is going on in the lifecycle of an HttpRequest between these two method calls that could be taking so long? This is IIS7 on Windows Server 2008.
I'm trying to get a reference to the user object in my Global.asax file's Application_BeginRequest. I'm using the property Context.User but I get a NullReferenceException. Is it possible to get a user object reference in Application_BeginRequest?
I am trying to create a 404 handling page but I am now stuck with the page only working for .aspx files, which isn't really what I need.I am running on IIS6.The site has a wildcard mapping,for extensionless URLs.All requests go through Application_BeginRequest in Global.asax but not all errors go through Application_Error.Is there a way where I can get the Application_Error to raise for non .aspx files?
We are obesrving strange problems when performing sress test of our applciation. We use Application_BeginRequest and Application_EndRequest to log the beginning and end of the web request, together, with the thread id.
However, from our logs, we see that Application_Begin_REquest is not being fired:
We use the following code to do the logging in global.asax.cs:
You can see that there are two "End request" in the last two lines, but there is no (Begin) Request for the last log line.Our Dbg.WriteLine uses System.Diagnostics trace listeners to ouput data to the file.
Environment: Windows Server 2008 R2, ASP.NET 3.5
This only happens when performin stress test. CPU utilization is around 60%, there are max 10 concurent requests executing.
UPDATE: I have found out that some other also did have similar problems (althoug in different configuration:
http://forums.iis.net/t/1154954.aspx) Matej
UPDATE#2: This night be related to fact, that Thread.GetHashCode() which is used to print out the thread identifier in our log fies could change. See ASP.NET - Thread.GetHashCode() changes
I created a web service on localhost, and I tried to call it from a web app (also on the localhost) via HttpWebRequest, but Application_BeginRequest in Global.asax didn't fire. When I type in IE 'http://localhost:8010/Test/' (the web service) Application_BeginRequest fires. Where is the problem? How can I test a localhost web service from a page which is also on localhost?
I have a problem using Application_BeginRequest and I have absolutely no clue what is going on. When using this code, my website works fine:
[Code]....
Now, when I only alter it like this (note that I am actually doing nothing special):
[Code]....
This small change in code causes that forms don't postback anymore. I am truely clueless why this happens when trying to get some request.form variables.Stupid thing is, when debugging the website using visual studio, everything works fine.
Is there a way to retrieving parameter names and values passed to a web method from Request object? I've read somewhere that you need extra code to access the soap body. Any known workarounds to be able to see the soap body from Application_BeginRequest?
I want to protect one file in a subdirectory with Global.asax. (I know that this isn't the conventional way of going about this) but it works on my computer and not on the server.I have a global.asax file in my root dir and Application_BeginRequest checks if the user is requesting a particular file. If they are logged in, it allows access. If they are not logged in they are redirected to the default page.My problem is this: My code works on my personal computer but does not work on the server. Do I have to configure a setting in the web.config or adjust something on the server? Code:
Sub Application_BeginRequest(ByVal sender As Object, ByVal e As EventArgs) Dim fullOrigionalpath As String = Request.Url.ToString.ToLower 'PROTECTED FILE If fullOrigionalpath.Contains("/uploads/groups.xls") Then If HttpContext.Current.User.Identity.IsAuthenticated = False Then Response.Redirect("~/login.aspx") End If End Sub
I fill a third-pard component variable in Global.Application_BeginRequest(). Everything is fine until I set IIS7 into the Integrated mode. In that case the method Application_BeginRequest() is not called (Application_Start is ok).May be some module is registered wrong?(I have found a same problem here on forum, but without a solution:[URL]
I am doing some redirecting of old url in global.asax's application_beginrequest. Redirecting works fine when getting the url's using an http get but not when using an http head request.
I want to implement hit tracking in an HttpModule in my ASP.NET app. Pretty simple, I thought. However, the BeginRequest event of my HttpModule is firing twice for each page hit. The site is very simple right now...no security, just a bit of database work. Should log one row per page hit. Why is this event firing twice?
Moreover, IHttpModule.BeginRequest actually fires a different number of times for the first page hit when running for the first time (from a closed web browser)...3 times when I'm hitting the DB to provide dynamic data for the page, and only 1 time for pages where the DB isn't hit. It fires 2 times for every page hit after the first one, regardless of whether or not I'm touching the DB.
It's interesting to note that Application_BeginRequest (in Global.asax) is always firing only once.
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.
I want to show on one of my pages a slideshow type page. Basically I want it to show a selection of images from a folder and have the images scroll from right to left.
I want to write one program by visual studio 2008 (C# and ASP) that has web application and windows application.
I want to get clients images in web app(upload) and store them in DB (mysql) then send these images to windows app via web service (so i new web service, not web site). But i have 2 problems:
I have 2 ways to store images in mysql, first i should have BLOB field in DB -that it takes more space-, second i should save just name of each image in DB(so have image in one folder) -in this way i don't know how get image from clients and store them in that folder-. which one? Or what other? How (code) can i transfer image via web service(Byte[] or? ).
how to upload images to server(application/images folder) and retrive(display) from and on client PC for asp.net. its just for uplaoding logo directly to server folder and retriving from server to client. i am not getting server path on client pc for image.
i have the following scenario, i have a column of a gridview that shows me a text telling me is the user is allowed or not to access to some page, but now i just showing allow and deny, but i wanna show images that represent me the action, how can i do that?
I wanted to combine app_themes css files into one on the fly. I did so using Mads Cristensen technique. But now all elements that has background image defined through css (see picture) don't display image. I believe that is because css files are not relatively referenced anymore (../), but through axd file. I'm trying to fix this by changing reference to image files without success. I already tried background: url("~/App_Themes/44/images/myimage.gif") and this works for pages that combined css. But the problem is that there are other pages in this project that don't use this css combining and now they lost reference to background images.
I'm using ASP.NET 4 Web forms routing, for example like this:
routes.MapPageRoute("page-browse", "{Language}/{Label}", "~/Default.aspx") So the webadress could look like: http://localhost/mywebsite/eng/home
In the root of my website I have a folder "Images".
Image display works when I'm in the root of my website, e.g. by using http://localhost/mywebsite/default.aspx
But when using routing it doesn't work, because the image relative url will look at http://localhost/mywebsite/eng/images instead of http://localhost/mywebsite/images
Is there a way to prevent this using ASP.NET 4 Routing mechanism? Or is the only way to use absolute url's to images?
I'm using an HttpHandler to display images from memory ... which is working fine.The image is displayed as a .png format in a popup window.My problem is printing the image from IE7 Web Browser using the popup menu displayed after doing a right-click, selecting 'Print Picture'.A blank page is being printed ... i.e. No Image, just the url and date on the bottom of the page and the page number on the top.I have also tried this with the image formatted as .jpg, with the same result.
