F5 and Member Configuration

Hi Yuva, looks like your Apache server does not link the HTTP health monitor requests from the big-ip that do not have the Host Header set. So you should try to update your http monitor on the big-ip to include the Host Header in the "send" string, and change the HTTP version to 1.0 or 1.1. By default, the http monitor is version 0.9.

 

 

Here is a link to the F5 Support Solution this explains this in more detail:

And here is a quick snippet from that Solution:

 

 

An HTTP version 1.0 GET request that includes two optional headers appears similar to the following example:

 

 

GET /index.html HTTP/1.0

 

Referer: http://www.domain.com/login.cgi

 

User-Agent: User-agent: Mozilla/3.0Gold

 

 

Let us know if this works!
