[Resolved] session_start() / PDF generation

[freebie]

I'm working on a PDF generator using the PHP class found at fpdf.org. The class itself works great. Where I ran into a problem was after adding session_start() to the top of the script (because I want to access some session variables), it no longer works (it returns a "save file" popup, but doesn't save or open. If I remove the session_start(), it works fine again. Does anyone have any ideas why this would cause a problem?

I found the answer to this on the fpdf.org FAQs page. It says IE has some problems when sessions are used with the pdf class. The workaround is to add session_cache_limiter('private');

before calling session_start();
