Jian,
i'll stand corrected on this by people more knowledgeable than i but...
It's true that WebOS will parse 10 frames or 4500 Bytes for the HTTP Header
you wish to use, but this is only until an instance has been found. Once
we've
seen the first instance of the header, we'll make the real server binding
and
"flush" the buffer used to hold the stings for parsing. In that same
HTTP/1.1
stream, if another GET requests is made with a new instance of that Header,
we'll change the server binding if the header is different.
This is obviously commonly done for URL parsing in 1.1 where multiple client
requests need to be parsed and issued to different reals.
Like I say, it would be useful for someone more technical to verfy.
Phil.

Subject: [load balancing] [Alteon]Header Hash Load Balancing
Hello,
We plan to use feature of "Header Hash Load Balancing" in AD3 to balance
traffic. The header of "Authorization" or "User-Agent" will be hashed. But
we were informed that if HTTP1.1 (persistant connection) is used, only first
10 packets or first 4500 bytes of traffic will be analysised. The real
server binding will be made basing on the header of first 10 packets or
first 4500 bytes. Then the rest of traffic will be directed to that server
always. Is that true ?
If answer is postive, is there any other work around solution. The cookie is
not allowed to use in our case.
Thanks for your help in advance.
Nice Weekend,
Jian
