Search and replace query string

[Chuck Vose]

Since I didn't get a response I thought I would try a second
clarifying email and see if it makes more sense to the people that
know.

We're trying to take urls like this:
example.com/api?test1=test2&test3=test4
and turn them into urls like this:
example.com/api/test1/test2/test3/test4

This is easy if there are a fixed number of variables in the query
string but we don't have that. Sometimes we have /test1=test2 but
sometimes it's /test1=test2&test3=test4&test5=test6&test7=test8, etc.
I think the most we'll ever have is about 5 deep but I'm not sure.

So is there any way to have a search and replace regex? I couldn't
find any examples of s///g regex's in the documentation. Do I need to
get mod_perl involved or do we need to move to apache? Maybe it's just
time to reassess but this seems like an awesome solution if we can get
it rolling.

Thanks again,
