Your web server is appending the SID to the images (and would to other links to the same webapp in the page) to track sessions, and is a common technique used by webservers to support sessions when browser clients don't support cookies.
I'm a little fuzzy on how exactly this works because it "Just Works", and some of the "old salts" on the list could probably explain it better, but here's what I think is happening. Some background, when a session-based request comes in, it sees if the client has also sent a cookie for the session. If not, assumes that the client does not have cookies enabled, so appends the session id to every link so that requests can be matched to sessions. For your situation, in the first request, a session is created, and since there will be no cookie from the client because it's a new sesion, the resposne to the client will include a cookie and a session id on links because the server cannot know if cookies are accepted or not. Why you don't see it after the first request is because after the first request the client is returning the session ID cookie. There is probably a much better discusson of how this works elsewhere, maybe at the Tomcat website. Also, I'm not sure what web server you're using, most use jsessionid; you could try searching for that on the list. You might be able to get around this by specifying a redirect=true for this initial page. -ed On 11/17/05, Aladin Alaily <[EMAIL PROTECTED]> wrote: > Hmmm... that's interesting. > > It looks as though I have no control on whether or not the SID is > appended.
