Mapping rule based on cookie

[Alex Sviridov <oo...@mail.ru>]

 Hello.

I need a reverse proxy which makes server mapping according to some value in cookie. 

For example, if there is a variable "key" and it is equal to 2 (key=2) then request must be redirected
to server 100.100.100.100. 

Can apache traffic server do that?

Think one way to do this would be:
- use the header_rewrite plugin to check the cookie value and set the
destination/origin Host. Not sure about the whole IP thing... perhaps
make up a domain and set /etc/hosts to 100.100...? Or just set the
Host to 100.100..?
- use the cachekey plugin to put the cookie value in the cachekey.

something like:
map http://inbound.example.com http://origin.example.com \
  @plugin=cachekey.so @pparam=--include-cookies=cookienamehere
  @plugin=header_rewrite.so @pparam=header_rewrite.config


with header_rewrite.config containing:
cond %{COOKIE:cookienamehere} ="key=2"
   set-destination HOST 100.100.100.100

not that i know but i am pretty sure you should start to describe your 
probklem and waht you try to achieve instead ask for a specific solution

in case of load-balancing the servers should use a shared session 
storage so that it don't matter on which backend machine a request ends
