Ideas to prevent cross-site scripting

 

An effective solution is to use htmlencode to encode the special characters so that they will be displayed but not executable. This line of code should come after the code gets the input value:

 

StrName=server.htmlencode(StrName)

 

The equivalent PHP code:

 

$StrName=htmlspecialchars($StrName);

 

Here’s a list of suggestions to help avoid the cross-site scripting problems:

 

     * Encode the special characters.

     * Check for the length of the input, either empty input or oversized might be dangerous.

     * Do not trust client side validation; validate the data on the server.
