How can I get HAPROXY to recognise that a server is up when a servlet is listening on a root context?

Question

I'm trying to setup haproxy so that http requests are routed to servlets hosted by websphere.

The servlets have a root context set so that:

wget  [host]:[port]/[root context] 

returns a response were as

wget  [host]:[port]

returns 404

How can I configure haproxy so that a proxy defined something like this:

listen MyProxy aaa.bbb.ccc.ddd:80 
mode http 
...      
server SERVER1 xxx.xxx.xxx.xx:8080 cookie SERVER_01 check 
...

doesn't result in haproxy reporting the server is down with a 404? I can't see where I can specify a root context.

Thanks

You just have to specify the URL to check using "option httpchk". For instance :

 option httpchk /index.html
