Url session id

Hi Guys
I am wondering if any one can give me any pointers as to so resources on urls
i want to submit a search but unlike some thing like the google url which is easy to identify the search criteria in the url this one doesn't. also it has a session id in the url which obviously changes each time you connect.

can these type of urls be split and rejoined to submit the query manually?

Code:

---

http://www.***.***.***.uk/EvlPortalApp/application;JSESSIONID_EvlPortalApp=LtdD15hJYvgjDXHMh3Flz4xKd1nrygnN9qZpLjWFTmkYbQTpyGk6!-1822535960!509171432?origin=vehicleEnquiryInfo_en.jsp&event=bea.portal.framework.internal.portlet.event&pageid=HONDA+LG57WFK&portletid=VehicleEnquiry&portletns=VehicleEnquiry_en&wfevent=link.next

---

i wish to be able to identify the peice of this url that contains the search crteira so i may add my own and also work with the session id.

I am not even sure of what i am trying to do is called to so i can't even turn up any good google searches. any help would be great.

hi nabbster,

Here's some information in regards to the url but i can't help with the session_id.
The url can be broken down and rejoined later, this is how it works.
Main link is http://www.***.***.***.uk/EvlPortalA...5960!509171432, all the way up to the ?
all the following parts are made up in any random order:
origin=vehicleEnquiryInfo_en.jsp
event=bea.portal.framework.internal.portlet.event
pageid=HONDA+LG57WFK
portletid=VehicleEnquiry
portletns=VehicleEnquiry_en
wfevent=link.next
all seperated by the &

Thats the basics so i hope it helps.
