equivalent for ModRewrite

[Alexander Widera]

hi,

perhaps you all know ModRewrite for the apache webserver... Is there an
equivalent for asp.net / iis? I don't want to buy a component (.dll)... I
want to program it myself. Some time ago, I wrote it with an custom
errorpage for error 404 which redirects it to the correct page. Perhaps
there is an simplier / better way?
Thanks for help, Alex

You can create an HttpModule and use Context.RewritePath to do URL
Rewriting. It's pretty easy.

Here they build an entire engine, it's pretty complicated imo but maybe
you'll find it useful:

This is an example for creating multilingual pages, but the idea can be
applied to anything you need

Hope that helps,

I tried a simple context.RewriteUrl("..."); but if I call an url (which
doesn't exists) i get an error message.

The complete code look like this (placed in the global.asax)

void Application_BeginRequest(object sender, EventArgs e)
{
HttpRequest request = ((HttpApplication) sender).Request;
HttpContext context = ((HttpApplication)sender).Context;
string applicationPath = request.ApplicationPath;
if(applicationPath == "/"){
applicationPath = string.Empty;
}
string path =
request.Url.AbsolutePath.Substring(applicationPath.Length);
context.RewritePath("/default.aspx");
}

I think this code should redirect every request to /defaut.aspx, or am i
wrong?
But I get the error: 404, page cannot be found.

What might by the problem?

Thanks for help,

Alex

If you want to redirect all requests made to .aspx files to default.aspx,
you should simply do

context.RewritePath("~/default.aspx"); is the BeginRequest....

that's what I tried (in a shorter way ), i tried this code too, but i get
the same Error.... if I call an non existing file in the filesystem....
404 not found... If the page exists, then the redirection works.

 

[Karl Seguin]

is it an aspx page that you are calling?

Ahh... now I understand.... You were right... If the "nonexisting-file" ends
with .aspx then it works ... but not if it ends with .html for example...
Is there a possibility that this works too with the ending .html except
adding .html to the list of interpreted extensions of the aspx-engine.

Thank you

The only way is the exception you mention...
