I’m writing a software for my company in PHP, using the Symfony 2 framework. I’ve finished all the work, created some sample data, it loaded perfectly. Now I put the whole thing into production and tried to upload the production data into it. Guess what… it didn’t …read more

Proxy only non-existing files with mod_proxy and mod_rewrite
