[Greasemonkey] Examing http response codes

Mon Dec 19 23:22:47 EST 2005

I think this all shows that sometimes it pays to be less tricky.
GM_xmlhttprequest is too high level for this.  It automatically forwards on
through to the new url and just returns data from my blog.

But I contacted the guys over at tinyurl.com and they clued me in to an
easier way.

So I'm going to just parse that page.  If there is some hack to catch the
actual 302 interrogation, I'd love to hear it.  That's likely to be more
dependable than page parsing.  On the other hand, if it takes any work on
the part of the gm developers, it's probably not worth it.  Keeping
gm_xmlhttprequest simple is probably more important.

Thanks for the help!
