Why do you think a port number would make a difference? As long as the
URI you're connecting to, correctly routes to something handling HTTP
- it doesn't matter - and since you're getting "script" tags back, it
implies it does.
I think the response you're getting says it all, although:
time it's omitted)
2) Can't fathom why the history.back() precedes the alert("...")
3) It's normally more polite to go to an error page with an <a
href="...">whatever</a> instead of an alert
For stuff like this, I would use Firefox with Firebug, and manually go
through the process of doing what you're doing, getting where the
posts go etc... etc..., and then try and mimic that.
ie, you find out where submissions take place and what data you
retrieve, it might be that you just require a session cookie and then
can by-pass pretty much all the intermediate pages.
If pages are AJAX generated, it's quite a bit more work, you'll either
need to run some form of web engine, or automate a browser using
selenium. Then you should be able to use lxml.html to parse the DOM
the browser has generated.
