hi...

this might not be a php question but might still provide interest...

I'm working on a project, and need to know if there's anyone who's a guru
with Web Server/Client interactions. Basically, I'm trying to get a much
better/deeper understanding of the HTTP protocols defining the information
that is sent/transfered between the web server/client browser apps.

I'm interested in understanding what the various information is that gets
transfered between the apps, as well as understanding what information can
be spoofed/altered on the client side, as it goes back to the server.

I know you can get the querystring information from the
get/put/request/etc... I'm more interested in any other information that
gets transferred as potentially part of the header structure, like machine
id, mac address, date/time, etc.... I'm interested in whether this can be
spoofed/altered, and potentially rendered invalid by a 'man in the middle'
type of attack.

Searching google isn't getting me what i really want!!

So, if you have the skills/expertise in this area, and you're willing to
talk to me for a few minutes, I'd appreciate it. As stated, the underlying
reason for the questions is to get a better understanding of 'man in the
middle attacks' as this applies to web server apps.

Thanks
