A plausible technique is the use of separating out the real content into 
things which require further loading--like requiring client-side 
scripting, cookies, use of CSS, iframes, images, embedded plugins (e.g., 
Flash or Silverlight), client-side redirects. You can then ensure that 
these things are also downloaded before accepting other page requests.

An additional factor could be if browsers actually use HTTP different 
from Java... e.g., if one pipelines and the other doesn't, or perhaps 
automatic SSL upgrading, etc. It all comes down to how many false 
negatives the server is willing to bear.
