[Zope] Strange Log Entries...

[zope at 2012.vi]

Hi;
My HTTP requests are passed through a Pound reverse proxy to Zope 
instances. I can hit all clients' sites fine, but some people can't. I'm 
getting the following entries in my Zope log which seem to detail the 
problem at hand:

NotFound: http://www.mrtablecloth-vi.com/verify-LAC_Compliance
NotFound: http://www.mrtablecloth-vi.com/notified-LAC_Compliance

These "pages" are not part of the Web site. What is "LAC_Compliance"? A 
Google turned up zero.

NotFound: http://www.livestocksling.com/1024 [ 
/eng/Swine-All_Products_frame ] 
This is indeed a page, but notice the brackets. Are these somehow 
originating in Zope?

TIA,
beno
