apache2 - Mod Rewrite problems -

i having problems mod rewrite. server ubuntu 12.04, apache2, php 5.4.

i want url this:

www.website.com/<modelname>/<imagenumber> 

and

www.website.com/<modelname> 

to show:

www.website.com/showimage.php?model=<modelname>&image=<imagenumber> 

and

www.website.com/model.php?model=<modelname> 

i have put in .htaccess:

rewriteengine on rewriterule ^([^/]+)/([0-9]+)/?$   showimage.php?model=$1&image=$2  [r,l,nc,qsa] rewriterule ^([^/]+)/?$            model.php?model=$1               [r,l,nc,qsa] 

i have checked mod_rewrite loaded in apache. page doesn't redirect.

edit: clarify, result 404 'the resource / not exist on server' , 'the resource // not exist on server'.

the strange thing playing around yesterday , tried make rule included website.com/model/modelname , seem in effect , impossible rid of. have tried restart apache ten times, clear browser caches , install browser didn't have before die-hard redirect yesterday keeps going in new browser (firefox).

are new redirect rules have written correct?

how put them in action?

should set chmod 777 on .htaccess?

thanks lot...

edit: here more information.

i have 1 (default) site , files (including .htaccess) sitting in /var/www

the file /etc/apache2/sites-available/default looks this:

 <virtualhost *:80>     serveradmin webmaster@localhost      documentroot /var/www     <directory />             options followsymlinks             allowoverride     </directory>     <directory /var/www/>             options indexes followsymlinks multiviews             allowoverride none             order allow,deny             allow     </directory>      scriptalias /cgi-bin/ /usr/lib/cgi-bin/     <directory "/usr/lib/cgi-bin">             allowoverride none             options +execcgi -multiviews +symlinksifownermatch             order allow,deny             allow     </directory>      errorlog ${apache_log_dir}/error.log      # possible values include: debug, info, notice, warn, error, crit,     # alert, emerg.     loglevel warn      customlog ${apache_log_dir}/access.log combined  alias /doc/ "/usr/share/doc/" <directory "/usr/share/doc/">     options indexes multiviews followsymlinks     allowoverride none     order deny,allow     deny     allow 127.0.0.0/255.0.0.0 ::1/128 </directory> 

i haven't changed there except directory / allowoverride all

.htaccess looks this:

rewriteengine on rewritelog "/etc/apache2/logs/rewrite.log" rewriteloglevel 9 rewritebase / rewriterule ^([^/]+)/([0-9]+)/?$   showimage.php?model=$1&image=$2  [r,l,nc,qsa] rewriterule ^([^/]+)/?$            model.php?model=$1               [r,l,nc,qsa] 

and have run service apache2 restart endless times.

this url works fine:

/showimage.php?model=ai&image=12 

this 1 doesn't:

/ai/12 

help!

rewriteengine on rewriterule ^([^/]+)/([0-9]+)/?$   showimage.php?model=$1&image=$2  [r,l,nc,qsa] rewriterule ^([^/]+)/?$            model.php?model=$1               [r,l,nc,qsa] 

rather going "this should work", i'll leave translating rules:

• the first rule match [anything]/[digits] or without trailing slash , re-map showimage.php?model=$1&image=$2 using redirect, break chain (i.e. second rule won't executed), case-insensitive (not needed), , preserves query string arguments. second same, model.php.

it important note second rule not match empty string (i.e. fetching /). might part of problem.

the rules correct. can test these on rewrite tool at: http://martinmelin.se/rewrite-rule-tester/ .

what believe problem is pretty simple. please answer following questions in comment , i'll advise there:

• are trying fetch / without index? if so, neither of rules matching , why you're getting 404.
• if not, exact url trying fetch? have access server logs? if so, can turn on rewrite log?
