WebAxe-1.pg

Alex,
We are trying to run the webaxe-1.pg workload in a reverse proxy
configuration.
There are problems we bumped into:

- Polygraph client robots send direct web requests (with no http://>/
  prefix in the URL) only when --proxy is not used. Therefore, client
webaxe-1.pg
  files should set
    srv_ips = <reverse-proxy-ip-address>
  which is not a polygraph server. Server webaxe-1.pg files should set
    srv_ips = <polygraph-server-ip-address>
  causing the workload files on the client and server to be different.
  Does this fact have any effect on the test? I tried it, and it worked.

- Polygraph robots detect the fact that they do not receive the response
  directly from a polygraph server. I suppose they are able to do so using
  one of the special polygraph X-...: headers. When this happens, I get
  a "foriegn name" error on the client. Does this have any effect on the
  test?

- We are currently running a test with one polygraph server. The hit ratio
  we see is very low - 30-40% instead of 0.75 * 0.95 (cacheable *
hit-ratio).
  I figure that webaxe-1.pg has the same problems mix3 had after moving
  to 2.5.4. Am I right?

- How do we simulate a configuration with more than 1 hosted server?
  To be able to do this, I need the ability to tell a robot that two
  web server names are on the same ip address, right? or is there another
  way...
   
Thanks, Ittai.
