Hi ,

As per my knowledge,when we submit a form then based on ENCTYPE attribute application/x-www-form-urlencoded or multipart/form-data is used by the browser to encode the form data.
But i have seen on some jsp pages that the value of input variables are explicitly being encoded using URLEncoder.Then on server side they are decoded using URLDecoder.What is the reason behind this?
Please let me know.

regards,
Ajse

Sounds like an approach to counter Cross Site Scripting attacks.

Special characters must be encoded if they are going to be part of the URL. When this isn;t being done by a form submission, it must be done "by hand".
