[tclwebtest] Problems with void redirection

[Grzegorz A. H. <gr...@ef...>]

Hi.

I'm testing a script against our server, but redirection fails. In
order to track down the problem (which I supposed involved cookie
handling) I added a new parameter to do_request, so that it can
be told to not follow the redirection, but return the new location
url. Patch attached (no_redirection_patch.gz). Now, after applying
that patch I tested this code:

   do_request http://www.efaber.net/
   
   log [cookies all]
   log "Trying to change language now"
   set url [link get_url Euskaraz]
   set url [do_request -noredirect $url]
   log "We were pointed at '$url'"
   log [cookies all]
   set url [do_request -noredirect $url]
   log "We were pointed at '$url'"
   log [cookies all]
   set url [do_request -noredirect $url]
   log "We were pointed at '$url'"
   log [cookies all]
   
   log "Now trying to do all automatically"
   do_request http://www.efaber.net/
   link follow {English}

The script does a manual redirection displaying the cookies'
values at each individual step. But then I discovered that
it's not a cookie problem. Attached is the log of the script
(no_redirection_problem_log.gz), it shows how the manual do_request
do well, accepting the cookies and setting their values. The last
automatic "link follow" command fails after the second redirection,
because it tries to follow a void url.

Just to verify that the http headers were correct (they send a void
Location field), I also attach the results of telnetting manually
to the server. It returns a manual redirection, also with a blank
value (no_redirection_problem_http_logs.gz).

How should I deal with this? I presume this blank redirection
AOLServer sends means that the browser should return to the
original url before the redirections started, but looks a very
awkward behaviour. Maybe this would require a "history" variable
in tclwebtest?

PD: It would be cool if link follow also understood the switches
of do_request, but I understand this is a little difficult because
it first calls link find.
