Header() not working?
I couldn't for the life of me figure out why header() didn't seem to be functioning - turns out it was because I had a blank line at the top of the contact-process.php page. That blank line, and in fact any blank lines in that code constitutes output and renders the header() function ineffective on account of there being a rule that the code cannot produce ANY output BEFORE you call the header() function!
Ok, that makes sense based on what else I've read. After the php tag you should be able to do other processing and have blank lines before the header.
