What is the difference in connection between css and html validators.  Do you use some special user agent string?

My colleagues wrote:

 "the site is filtering based on user-agent, and explicitly filtering the markup validator's UA string"

 "ok, with mozilla or wget UA string => ok, if I use the markup val UA string (W3C_Validator/1.3), it timeouts"

Hope that helps...
