DELPHI AREA Forum

Hello
I want to write an application that trace outgoing and incoming TCP/IP packets (works similar to a firewall).
for example: if the user requests "www.google.com" and receives the html content of google home page,I can modify received data.
how can I do this with delphi?

go to http://sourceforge.net/projects/isafer/ and download the source code for a windows firewall developed with delphi then add what ever you want to it.
