http://issues.apache.org/bugzilla/show_bug.cgi?id=43319 Summary: when combined with mod_proxy, mod_rewrite NE flag does not work correctly Product: Apache httpd-2 Version: 2.3-HEAD Platform: Other OS/Version: All Status: NEW Severity: normal Priority: P2 Component: mod_rewrite AssignedTo: [email protected] ReportedBy: [EMAIL PROTECTED] I was trying to send %3d to backend server as a reverse proxy. --[Conf With rewrite rule RewriteEngine on RewriteLogLevel 3 RewriteRule ^(.*)test.txt$ http://agneyam.india.sun.com:2000/val\%3dtest.txt [NE,P] ] >[ GET /http/me/test.txt HTTP/1.0 ] gets sent to back end as >[ GET /val%253dtest.txt HTTP/1.1 Host: agneyam.india.sun.com:2000 Max-Forwards: 10 X-Forwarded-For: 129.158.224.203 X-Forwarded-Server: agneyam Connection: Keep-Alive ] ie, the % gets escaped again. If I remove the [P] from the flags, the url generated is correct.
