[Mediawiki-l] Upload Problem

[Con Rodi]

I have seen this problem intermittently on several MediaWiki versions  
(1.3.9, 1.4.2, 1.4.4) over the past six months.  I'm on a hosting  
service that gives me no visibility or control of the various Apache  
settings.

I did spend a half day trying to track this down and found out the  
PHP session variables that hold the file parameters were not  
persistent after the verification page.  The images were indeed being  
uploaded to the server, but the session variables were lost.  In the  
midst of my debugging, things suddenly started to work.  I reverted  
back to the original PHP code and life was wonderful.  Since my  
immediate task was to upload a large set of images, I pressed on with  
that task instead of trying to figure out what was previously not  
working.

I'm still perplexed.  Unless someone at my hosting service is  
randomly flipping Apache parameters, I don't see why the  
LimitRequestBody directive is a likely candidate.  Something related  
to session management seems more suspect.
