php - mod_rewrite changing address bar for no reason -

i have .htaccess file , when ever type www.example.com/demo/index.php keeps redirected me in loop. i'm confused why happening.

# not remove line, otherwise mod_rewrite rules stop working  rewritebase /  options +multiviews  addhandler application/x-httpd-php .css  addhandler application/x-httpd-php .js  rewriteengine on   #nc not case sensitive #l last rule don't process futher #r 301 changes url want  rewriterule ^demo(.*)$ finished$1 [nc]  rewritecond %{request_uri} ^/finished/.*$ rewriterule ^finished/(.*)$ demo/$1 [nc,r=301,l] 

i can see rewrite loop happening if doing:

http://mydomain/demo/rewrite.cgi 

because rewritten first rule to

http://mydomain/finished/rewrite.cgi 

and matches rewrite condition of second rewrite rule , gets rewritten to:

http://mydomain/demo/rewrite.cgi 

and loop starts.

there's 2 fixes here either a) add l flag first rewrite rule (makes last rewrite happen) or b) if demo rewrite not followed slash i'd make implicit:

rewriterule ^demo([^/]+)$ finished$1 [nc] 

the other option if that's not cause, turn on rewrite rule logging , @ being done create loop:

rewritelog /path/to/rewrite.log rewriteloglevel 3
