I tried adding a form to our website for uploading large files.
Personally, I dislike the forms that tell you you did something wrong
and make you re-enter *all* your data again, so this one cycles and
remembers your answers, and only prompts for the file once the rest of
the entered data is good. However, the first time the form loads it can
take up to 30 seconds... any ideas why?
Hard to tell without looking at the code... And what has cgitb to do with this?
Hmmmm... excellent question, and the answer is -- Nothing. My
apologies. I'm importing cgi (cgitb was while I was debugging it), as
well as a bunch of others.
Here's the source, with a bunch of the actual html stripped out. The -u
as well as the last two lines were an attempt to eliminate the 30-second
pause while it loads, as it seems to get all data transferred, then just
waits for a while. Any ideas appreciated. My apologies for the ugly code.
