URL Mapping

[Guest]

I want mapping any url to a certain .dll to process. For example I want all
requests to URL http://myserver/vpath1 or http://myserver/vpath1/anyfile be
redirected to myhandler.dll to handle. One important thing is that the URLs I
want to redirect may not physically exit, they could be just virtual URLs.

Thanks!

hi Jingxi,
i wrote an ISAPI filter that does just what you describe. the reason i
used ISAPI was because i wanted to have virtual folder URLs aswell as
page urls. so you can have myserver/Folder1/Folder2/ which gets
redirected to your DLL for server processing or whatever.
i have it set up to intercept all .html requests and requests for a
default document (i.e. for a folder) and to redirect them to
/content.aspx?Url=THE_ORIGINAL_URL.HTML

it ignores all other types of requests, .aspx, .asmx, .jpg etc.
you can see how i did it on my blog, and download the ISAPI filter. if
you have VS.Net, you can modify the solution to whatever you need.

there are easier ways using the .Net framework, like setting up a new
script mapping for a file extension in IIS, i.e. you can set IIS to
treat .html files as .aspx files. but none of these options work with
non-existent foleder URLs. also, this filter logs the original url
that was requested, instead of /content.aspx?whatever... for each
request. the original url is presumed to be more interesting..

let me know if this helps your situation.

thanks
tim

Ian has discussed this:

http://www.interact-sw.co.uk/iangblog/2004/01/12/shinyurl

and http://www.interact-sw.co.uk/iangblog/2004/01/14/rewritingurls

and there is a MSDN article:

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnaspp/html/urlrewriting.asp

And these are all done in ASP.NET. The ISAPI is also not a bad idea, but
it's probabaly going to be more complicated (code wise).

i agree with brock.
but... if you want virtual folder urls, then ISAPI is the only way as
far as i know.

Thanks a lot for your informative inputs and the project you shared with
us, Tim_Mac,

Hi cjx,

I totally agree with Tim_Mac , if you want to intercept all kinds of coming
request (url contains an document extension or only a directory url ....),
the ISAPI filter is the only solution. ASP.NET's UrlRewriting can perfectly
handle dynamic document(with a certain extension)'s request redirection but
can not work for folder path.

Thanks,

Steven Cheng
