Monks,

A CGI script that takes in a number of text fields and writes them to a text file seems to be truncating some of the larger strings. This script has been working fine for over a year now, and the one thing that all the truncated strings have in common is that they are exceptionally long (> 7 pages of text), so I don't think it's a problem with the script logic.

All the script itself does is grab the strings from the query params, throw them into string variables or hashes, perform regular expression type magic, and write them to a file. I don't think there is a problem with the regexp, because they are pretty harmless "remove certain characters" pattern match and substitution. And they are only truncating the fields with very long strings--I would expect a bad regexp to trash everything.

The strings seem to be getting truncated in the neighborhood of 46060 characters (~45k).

My questions:

• Is there a limit to the size of a name/value pair that CGI can handle using method=POST?
• Is there a limit to the buffer(?) size that perl uses for regexp?
• Is there a limit to the buffer(?) size that perl uses to write to a filehandle

Thanks,
Chris
