I have an application written in PHP using Codeigniter sitting on a LAMP stack. Our tester has a very strange error that I am unable to replicate on any other machine. Whenever she sends a request to the test server that contains a space (and I assume any other characters that need encoding) the request just hangs and never gets a response. The same request to the live server works fine. The same request to the test server from any other machine also works fine. So I thought that perhaps there was a problem with the charset used in the request or the response. I have checked the default charset in Apache and PHP and they are both set to 'UTF-8'. Any suggestions/thoughts/pointers? I have a feeling I am missing something simple which is just escaping me at the moment.
I found out what the problem was... Although I do not know or fully understand why it would occur. The tester was the only machine using the proxy server on the network. I removed the use of the proxy and everything works fine...
