Subject: IE sp2 and Mozilla Firefox DoS.

There is an issue with these browser rendering html's
with long titles. 
Only Tested on: 
-------------- 
Internet Explorer(SP2): 6.0.2900.2180 
Mozilla firefox: 1.0 

Not affected:
------------- 
Mozilla Browser 

Have a look at,

For IE beyond 1 Mb will just do fine. On execution,
Mozilla Firefox starts filling up all the available
system memory with 100% CPU use. 

Internet explorer renders 100% CPU use, but no system
instability. (O; 
I've tested it on Windows XP SP2. 

Both Firefox & IE supports decompression method 'gzip'
ie. an extended request header named
HTTP_ACCEPT_ENCODING like 
HTTP_ACCEPT_ENCODING=gzip,deflate 

By this way, the file can be kept around few kilobytes
in the server and delivered easily. I wonder, why
such... simple issue went un-noticed to everyone for
years...
