Re: [WEB400] 302 Redirection Headaches

[daparnin@xxxxxxxxxxxxxxxxxx]

Brad,

Wow.  You've come to my rescue twice in one week.  I might just have to put
you on my Christmas card list this year.  <g>  If you haven't guessed I'm
new to this stuff (but learning fast).  I wouldn't have guessed it but
passing the cookie info back and forth does make sense as a method of
"logging in".

So, in my situation where it redirects from A to B to C back to A then I
should probably look for the cookie in the header when going from A to B
then pass it back when posting to B and hope that I get redirected to D
instead of C, correct?  I'll have to keep an eye on what the values are
when I debug it a few times.

I'll give it a shot and see what happens.  Thanks!

They're most likely using frames... so what you need to do
is view the source for the page with the input fields on
it, and do a POST to the path specified in the form on the
action tag sending along the appropriate data fields
(hidden or not).  I doubt you'd use the API or any other
tool to go to a root domain.

After "logging in" many times you will be returned either a
cookie or a session ID.  That needs to be saved and sent in
the header of any subsequent request so it thinks you're
still "logged on".  Sometimes apps can be picky as to how
te headers with cookie/session data are returned, so it
will take some time.

I've helped many customers in similar scenarios do this
exact same thing with my GETURI application.  Some use
cookies, some use session IDs.  Either have to be parsed
from the returned header for later use in following
requests.
