Mimic a web surfer ?

[shagshag13]

hello,

i would like to develop a script which will mimic a web surfer, that is :

- follow links as a human and thus always come from previous page (i think
there is something to do with http 'referer' and cookies)
- be able to log if necessary

is there anything already existing ? i'm looking for any tips which will
help me to start...

note : this could be used to have "automatic" access to free webmails not
providing pop protocol.

thanks in advance.
