Re^2: GET request using LWP::UserAgent returns 200 OK but Firefox 302 Found

[bliako]

Good thinking! Indeed there are other GETs before the ones I described (in a previous phase which completes successfully) so the cookie actually is set. thanks.

I think I am getting closer though but I still have to test it:

after using

Wireshark as per 7stud's and haukex's advice

and

LWP::ConsoleLogger::Easy

I realised that LWP::UserAgent could be responding to a '302 Found' automatically and follow the redirect. And that BOTH me (via LWP) and LWP (responding to the 302 automatically) are sending another request to the re-location (however, I am sending one after LWP finished with his). And that messes things up.

Man page of LWP states that there is a list called 'requests_redirectable' which contains the protocols for which to follow redirects. By default, 'GET' and 'HEAD' are included. POST is not.

Given also that LWP's 'max_redirect' is 7 by default, it sounds to me that a GET returning with a 302 will cause LWP to follow automatically. But I am also doing that myself in the program having assumed that LWP will not follow redirects (or forgottent that it does).

In my 'scraping exercise' there is a long list of previous POSTs which return a 302 but this is the first time GET does. The POSTs were not followed on by LWP and all was OK but the GET is (because it is in the 'requests_redirectable' list of LWP) and the problem arose.

thanks
