I thought I ought to raise visibility of this (302) here as well. Recently-ish search engines have stopped spidering your site when they encounter an http code 302 - redirect. This is due to page-jacking / spammers and an attempt to counter that problem.
I’ve begun discussing the issue here in relation to RainbowPortal 1.1:
So far we believe it’s about sorting out Global.asax’s BeginRequest method although my concern goes further into general cookie management and what’s best to deal with the 302 issue.
Any ideas welcomed…
