tphyahoo has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to fetch a web page, follow a javascript redirect, and verify that a string is found at the landing site.

If you copy/paste the url below into a browser +e=idealo-de&serviceType=portal&oid=1066de515358&sid=73&pt=idealo-de.e +xport.1-0& +2FWFS%2FBaur-BaurDe-Site%2Fde_DE%2F-%2FEUR%2FBV_ExternalCall-Start%3F +ArticleNo%3D515358%26NUMSArt%3D4443504%26NUMSArtPc%3D4488615%26Affili +ateID%3Dpangora-%2A%26Name%3Dpangora-produktdaten-baur%26ActionID%3Dp +reis-produkt-suche-baur%26WKZ%3D79%26IWL%3D101
you see it redirects to a web page whose page source should match the regex (eg, the price "249,90"). However, WWW::Mechanize cannot follow this redirect -- although in general, mech is usually pretty good about redirects. I think this is a server side redirect.

I realize I could attempt to parse the html on the obtained page, which has some text to the effect of "if you were not redirected, try here." However, I have many groups of such pages I would like to follow redirects with, each of which would require a parse (and some of which might not have a "if didn't redirect, try this" text to parse), and I'm wondering if there is a more general solution

I tried WWW::Selenium, but was unable to get it to work. I suspect this is because selenium is beta-ish, and maybe my environment is just selenium unfriendly. I'm on linux, suse, firefox 2.

Can anyone get this to work, with Mech, Selenium, or something else?

Thanks in advance!

UPDATE: changed "server side redirect" to "javascript redirect"

UPDATE 2 getting closer, but still can't do what I want:
