massive Issue with Caching and ModExpire on php Files

Question

I do have a massive Issue with Caching and ModExpire on php Files if i\'am using following in my global .htaccess

 ExpiresActive O         


        

Answer 1

To prevent php files from caching try to remove ExpiresByType application/xhtml-xml, which is for PHP.

IMHO you can also remove FilesMatch for PHP files.
