I need help with an URL rewrite rule

Question

0.00/5 (No votes)

See more:

First a bit of background, I wrote an ISAPI Extension in C which turns PowerBuilder (a desktop app language) into a web language.

I am trying to create a URL Rewrite rule so that I can support the REST friendly URL pattern.

This is the URL I am trying:
http://localhost/topwizweb/api/resttest/one/two/three

This is the result that I want:
http://localhost/topwizweb/api/resttest.pb/one/two/three

Note that .pb is the file extension I am using for the PowerBuilder code.

What I have tried:

Here is my rule currently:

Pattern: /api/(.*)
Rewrite URL: {HTTP_HOST}/{R:0}/{R:1}.pb

The incorrect result I am getting:
http://localhost:80/localhost/api/resttest/one/two/three/resttest/one/two/three.pb

Solution 1

{R:0} is the entire input string, which includes {R:1} and the host.

{R:1} matches the entire URL after /api/. That ends with three, not resttest, so you end up adding .pb in the wrong place.

Try:

Pattern: ^api/([^/]+)/(.*)$
Rewrite URL: api/{R:1}.pb/{R:2}

Doesn't work. The .pb doesn't show at all.
