RE: Large File Upload Fails

David,

There is a default maximum size for POST data. You can change it but I
don't recall the directive you need to add. Take a look at the version
2.0 documentation at http://httpd.apache.org and you should be able to
find it.

Subject: [WEB400] Large File Upload Fails

I have a Java web application (running on Apache 2.0.49 for the AS400 
and WebSphere Application Server 5.0.2.7) that allows the user to upload

a file (via HTTP), where the application then takes it and writes it out

to disk.  For every file smaller then 9MB or so, everything works 
great.  If the user tries to upload a file that is greater then that, 
then the browser comes back after about 30 seconds with a message saying

"Document contains no data".  If I were to take an 18MB file and split 
it into two 9MB files and upload, that would work.  So it is not a total

size issue but appears to be an issue with the size of a single file.  
By the way, I do all the development work on a Windows machine and the 
upload of a large file works in that environment.  Also of note is that 
when it fails it never even reaches my application code so doesn't even 
try to write it to disk.  It appears to be failing on the web server 
side before it even gets to the app server.  Does Apache on the AS400 
have some type of file size limit?  Or a cache size limit?  Or perhaps 
the HTTP connection times out after 30 seconds?  Does anybody have any 
suggestions/ideas?  Thank you.
