403 forbidden after installation of mod_pagespeed

[Komal Khushal Dubey]

After installation of mod_pagespeed I am facing the problem, css and js files which are rewritten by mod_pagespeed they are causing the 403.

If I remove the rewrite related filters then it works fine.

Hi Komal -- I'm moving this discussion over to mod-pagespeed-discuss.

Usually, if your server is giving 403s after MPS is installed, it is related to mod_rewrite or some other configuration that you have that doesn't expect mod_pagespeed to rewrite URLs.  In some cases (e.g. combining CSS or JS files), a set of files in lower level subdirectories may be moved up, which might not play well with your configuration.  E.g. if you combine

   a/b/x.css

   a/c/y.css

MPS will generate their combined result in URL

   a/b,_x.css+c,_y.css.pagespeed.cc.HASH.css

If you have Apache directives that forbid loading out of a/ but allow loading out of subdirectories of a/ that would then be consistent with your observation.

One possible remedy is to start off using mod_pagespeed in a manner where it makes resources smaller but doesn't change URLs.  Check out https://developers.google.com/speed/pagespeed/module/optimize-for-bandwidth

Another remedy is to make sure you don't have other Apache directives that would disallow the URL patterns PageSpeed generates.

If you are using apache it's posible that pagespeed mod is rewritten URL segments greatest than 250 characters and apache server has a further limitation of about 250.
