rewrite query string

[Thomas Seifert]

Hey folks,

I simply can't figure out how to rewrite the query string in nginx.
I need to turn urls like foo.php?f=111 into foo.php?111 and similar things.
 From reading past messages in the lists it seems like I can only match 
on query string with the "if" but
there's no way to rewrite the query string itself.
Is that still correct? No workaround available?


Thanks in advance,

thomas
