That WO application is external site and I have no access to it.
I've analyzed HTTP requests and responses of my browser and external server with Firefox Add-on - Tamper Data. My browser always sends only one set of cookies(with the same values) wosid, woinst and JSESSIONID. And external server never asks to set another set of cookies.

About the URL I send POST request to...
This WO app uses frames. Each page(main page, page with the registration form) consists of two frames "header" and "content". URL of main page(is constant): /KursPlattform/WebObjects/KursPlattform.woa/wa/UAAuthDA/auth?par=G5n9SoCPUIqm93qsNXWNH45V0
And URLs of two frames(header and content):
/KursPlattform/WebObjects/KursPlattform.woa/wo/0.1
/KursPlattform/WebObjects/KursPlattform.woa/wo/0.3
These URLs change each time when i refresh the page...

The situation with the registration page is the same:
Registration page URL(it changes after refresh): /KursPlattform/WebObjects/KursPlattform.woa/wo/3.5
And URLS of it's frames(they change too after refresh)
/KursPlattform/WebObjects/KursPlattform.woa/wo/4.1
/KursPlattform/WebObjects/KursPlattform.woa/wo/4.3

A form "action" URL at first is /KursPlattform/WebObjects/KursPlattform.woa/wo/6.3
But it also changes after I refresh the page..

I've found out the urls that server gives me after i visit site after cleaning my browser's cache, cookies etc..("first visit") I wrote a code to save the set of cookies that server gives me after the first request to the main page..
I send all this in a post request, but see a "backtracking" error.

Maybe WO application deletes the session after the first GET-request too soon, so that when i send second request(POST) server "don't remember" this set of cookies...? How WO applications usually stores it's new sessions? Is it possible to write a code that will act on that external server like a browser(i mean using one session for several requests and responses..)? Are there some common behaviours in the WO applications for this case?
