[MacPerl-WebCGI] Filters

[tedd<tedd@sperling.com>]

Hi:

How does one control what a user enters in a text field when 
gathering information via a perl cgi script?

Such as: 1) To filter the text to remove anything that could be 
malicious (basically keeping a-z,A-Z,0-9, and standard punctuation 
'.;:-' with quote marks; 2) And, to keep the length of the input to a 
certain limit of characters.

Are there standard routines for this? It seems like it would be a 
common concern.

Many thanks for any replies.
