Hello,
I have a page where i can upload binary file (using the HTML input
type=file approach). This works fine for relatively small files
(<6MB)) but when files get bigger (13MB) there is a problem.
The code of the php file is based upon the article in
http://www.onlamp.com/pub/a/php/2000/09/15/php_mysql.html: uploading
large binary files using more than one table and more trhan 1 row per
file.

Hi,
I am writing an ASP.NET project where I allow users to upload files to
the server. I have changed to web.config to allow a total file size of
100MB. My problem is that if the total file size exceed this amount the
page simply stops works, and I get a "Server unreachable" error.
Is there any way to handle this, so I am able to present the user with
a nice error message telling him that the maximum file size has been
exceeded.

Hi there,
When adding a "File Field" HTML control to an aspx page to facilitate file
uploading, the following occurs:
1. You select a file that is larger than the allowed size limit.
2. Once the user selected the too large file, the page is redirected to a
"page not found" error page.
3. This is as per the docs, but my question is:
