Hi,

I have added some code to the HTTPModules DNN Source project in the UrlRewriteModule.vb file.

All it does is the following in one location in a few dozen lines of code:
1. temporarily hijack each request,
2. check the requested URL against some Cache
3. If there is a match, Call RewriterUtils.RewriteUrl
4. Hand the request back to the rest of the code. It often gets rewritten twice (once with my new code, once again with the native code), because this method allows me to redirect   domain.com/stores/my_super_pretty_product.aspx to domain.com/products.aspx?StoreID=12&ProductID=15. Since I'm handing it back to the "regular" DNN rewrite code (instead of replacing it), that URL then gets rewritten to domain.com/DEfault.aspx?TabID=73&StoreID=.......

This works quite nicely, but it will make it hard for me to upgrade DNN, since I have updated some core DNN stuff here.

Is it possible for me to override a function with my own version (an extension perhaps?) while calling the original as well? Please keep in mind, I like the default functionality... I just want to add this quick Cache-Lookup first.... and I really don't have to have to try and bring in all of the core DNN code into my own extension.

I'd like to do something like the following in my own sort of extension or something:

Public Overrides Sub RewriteURL(...)
   .... do my cache check / potential rewrite ...
   MyBase.RewriteURL(...) 'Now, execute the standard code
end sub

Sorry for the poorly written question. Doing the best I can... the extent of my DNN programming has been with custom modules. I'm still a bit overwhelmed by extensions.

Thanks

 
Chris, the sounds like a great idea. Thanks for the solution!
