My mod_rewrite
rules are working fine but sometimes similar errors showing up in my error logs:
File does not exist: /var/www/examplesite/exampleurl
Of course the requested directory doesn't exists, page properly served but my error logs growing.
What can cause these errors?
You should probably start by changing the loglevel for your rewrite engine:
http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html#rewriteloglevel
This should help diagnose if there is an issue with the rewrite rules or perhaps some other parameters for the client requests(perhaps they have incorrect Host parameters, etc).
