Reading and parsing data packet from and to, a Web Server !!??

[Papik]

Hi people ! I'm looking for a program (free better, open source better) that sit between a Web Server and a Browser and can read all the data, both ways, to let say write the data to an ascii file (for example) or to a database.
Is there any interesting program you know about ?
Thanks a lot !!

Tea Leaf Technologies has got a great product but it is expensive. They had a client-side capture tool that was free but I think they've bundled it into hte whole package. Their package is geared toward server operations.

For a very effective (and FREE) ethernet sniffer, try Ethereal from

http://www.ethereal.com.

It captures and decodes packets very nicely.

Hope that helps.

Sniffer might help you but it is not free.
Snort is free but I do not use it before merely hear of it.
