GoogleT5

I take it the "GoogleT5" is Google Transcoder version 5?

66.249.85.84 - - [10/Sep/2008:21:15:58 -0400] "GET /scripts/menu.js HTTP/1.0" 403 - "http://www.apassion4jazz.net/jazz_styles.html" "User-Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0; GoogleT5; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.0.04506; InfoPath.2; Tablet PC 2.0)"

This got blocked because of the "User-Agent:" part which I filter due to SPAMers pounding my input forms.

No clue, but I boot anything claiming to be a browser with "HTTP:" in the user agent, and the "User-Agent:" thing as well. I whitelist the top 4 SEs first since they have HTTP paths in their user agents and then anything else with HTTP goes into the trash.

Yes, I'm a big meanie ;)

The GoogleT5 part is apparently a new version of the Google Toolbar.

The Mountain View IP may well be a publicly accessible tool of some sort.

The User-Agent prefix always gets the thumbs down from this little meanie.

This is a visit of Google Toolbar used component of tapestry 5. Do a Google search by: [google.com...] you will find the full Information.

Based on the behaviour I've seen from the UA starting with "User-agent", many of the sessions look like the AVG LinkScanner security pre-fetching we discussed recently.

Because of this, I've been serving a small page with a note about our site not supporting pre-fetching. The page includes CSS and image references which are never fetched by these user-agents. However, there is frequently another session immediately following from the same IP address, where the user-agent and browsing behaviour is completely normal and human-like.

However, after taking a look at Tapestry, I've modified the logic to block any UA starting with "User-agent" unless it starts with "User-agent: Mozilla/4.0 (compatible; MSIE 6.0;". This would block the UA being discussed here based on the MSIE version -- without requiring a "T5"-specific pattern, although it might be a good idea to include such a pattern.
