HttpHandler trouble

[vbkris]

hi all,

i want to block the users from accessing certain extenstions like .swf in my site (not using IIS).

i want to know the best way to carry this out. currently i tries using HttpHandlers. it doesnt work.

My code:
Config code
<httpHandlers>
<add verb="*" path="*.swf" type="SwfHandler,SwfHandler" />
</httpHandlers>



My SWF handler code:

Imports System
Imports System.Configuration
Imports System.Web

Public Class SwfHandler
Implements IHttpHandler

Public Sub ProcessRequest(ByVal context As System.Web.HttpContext) Implements System.Web.IHttpHandler.ProcessRequest
Dim request As HttpRequest = context.Request
Dim response As HttpResponse = context.Response
response.redirect("

http://google.com")

End Sub

Public ReadOnly Property IsReusable() As Boolean Implements System.Web.IHttpHandler.IsReusable
Get
Return False
End Get
End Property
End Class



some doubts:
I created a HttpModule prior to this. When i tried to use it in a sub folder's config file the <httpModule> tag didnt work. When i put it in the root folder's config file tag it worked. Am i doing anyting wrong???

i forgot to mention my understanding of handlers:

1. user enters

http://localhost/1.swf

2. the request goes to IIS
3. IIS hands it over to HttpHandler
4. Handler redirects the user.

Note: 1.swf acutally exists on the server...

Is there a particular reason that you don't want to use IIS (i.e is it because you don't have access to IIS as it is a web hosting company that you are using)?

If so, then a lot of web hosting companies will do the work for you. They will configure IIS to map a .swf file to the ASP.NET ISAPI extension, then all you need to do is add the httpHandlers section to your web.config file.

If this is an option for you, see the following for more info:

>>is it because you don't have access to IIS as it is a web hosting company that you are using

yes


hmm, so only .ASPX files pass through IIS huh (is .axd a configured format cause it seems to work for .axd)...

yes

In that case it may be worth asking if they will do what I suggested above.

No, all extensions pass through IIS. IIS then uses it's application mappings list to see which file to call in order for the file to be handled.

so is .axd listed?

i have an example for .axd (in a book). if the author is giving an example for .axd then it must be available to all IIS. just wanted to kown if u have used a file in that extension in .NET...

Yes, axd files are handled by the aspnet_isapi.dll

Did you ever get this to work? It looks ok except the class name should be fully qualified including the namespace.

fully qualified?

like ca8msm said i had to change IIS handlers...
