Mod_rewrite：重定向到查询字符串中的URL-从重定向URL的末尾丢弃％3f

Question

I have an .htaccess rewrite rule which takes incoming requests of the form:

IN 1) http://some.domain.com/path/to/index.htm?url=http://take.me/
IN 2) http://some.domain.com/path/to/index.htm?url=http://take.me/another/path/file.htm?key1=val1&key2+val2

What I want to do is have the rule extract the value of the url key and redirect to its value, ergo:

OUT 1) http://take.me/
OUT 2) http://take.me/another/path/file.htm?key1=val1&key2=val2

The following condition and rule works:

RewriteCond %{QUERY_STRING} ^url=(.*)$
RewriteRule ^index\.htm$ %1? [R,L]`

However in the case of OUT 2 I'm finding that the resultant URL seen in the browser address bar is:

http://take.me/another/path/file.htm?key1=val1&key2+val2%3f

So the problem is that a %3f (percent encoded question mark) is appended to the resultant URL. The problem is caused by the use of the ? in the RewriteRule, but I need that so that the original query string is discarded. I do not know if the %3f will cause problems, so to be on the safe side I would like to eliminate it. We're using Apache 2.2.22 so no Query String Discard [QSD] option unfortunately.

Is there a way to eliminate the %3f while maintaining the function of the rule?

Answer 1

You can use this rule with NE flag which means no escaping resulting URL:

RewriteCond %{THE_REQUEST} index\.htm\?url=(\S+) [NC]
RewriteRule index\.htm$ %1? [L,R=302,NC,NE]
