Hi Wesley,

The problem is shown in Google Webmaster Tools, not my browser. In
Webmaster Tools (labs -> site performance) it shows ways that you can
speed up your site. This includes telling you if GZip isn't enabled. I
can't check what headers GoogleBot/Webmaster Tools (?) are sending,
but I imagine if they're checking for GZip, they're sending headers to
say they support it (though exactly what, I can't say).

If it's just a case of App Engine not understanding that GoogleBot
supports GZip properly, then it's not a big issue (since it'll still
be zipped for visitors), but it would be nice to confirm that. Is it
possible you can contact the person/people that worked on the Google
Webmaster Tools Labs / page speed tool to verify? I don't think our
App Engine logs have enough info to diagnose the problem (short of
adding code that checks for GoogleBot and logs the headers, but I'm
sure you can find that out faster working for Google ;-))

Danny
