Description

Attached is a simple user-contributed (e.g. no guarantees) patch to expand the capabilities of mod_redirect for lighttpd 1.4.8.

It adds two features:

  • optional url-encoding for backreferences
  • allow backreference character usage without substituting a backref.

Here is an example of the first case:

Let's say that you want to map the specified URL into a CGI argument, but you want it to be escaped properly --


 url.redirect = ( "^(.*)$" =>
                  "/view?path=$!1" 

If a user requests "http://example.com/special/documents?foo=bar", they will be redirected to "http://example.com/view?path=%2Fspecial%2Fdocuments%3Ffoo%3Dbar".

Now let's say you want to include an absolute address so that the user is redirected to a different site, http://2.example.com. You would want the redirection to result in the following URL: "http://example.com/view?path=http%3A%2F%2F2.example.com%2Fspecial%2Fdocuments%3Ffoo%3Dbar".

The second change allows you to do this with mod_redirect:


 url.redirect = ( "^(.*)$" =>
                  "http%%3A%%2F%%2F2.example.com/view?path=$!1" 

Using double percents, mod_redirect will no longer assume that the %3 in %%3A is a poor backreference and it will print out the desired single %.

Doh - it looks like I need to attach after I file the ticket. If I have a problem with it, I will put it on the wiki as an attachment.
