Apache configuration for Windows Network Load Balancer(WNLB)

[ponvin]

Hi All,

 

We have two Apache Web Servers running in windos machines and they are communicating with Clusterd JBoss servers by ModjK configuration.

 

Fronting the two apache web servers we have an IIS server which communicates to apache web servers using ISAPI Rewrite software.

 

For load balancing these two apache servers we have configured the Windows NLB and assigned the Virtual IP address for NLB.

 

1.2.3.1 => Apache 1

1.2.3.2 => Apache 2

1.2.3.3 => NLB Virtual IP address

 

When we access the application using the Apache 1 IP address and Apache 2 IP address we are able to access the application on the browser.

like http://1.2.3.1:80/example & http://1.2.3.2:80/example are working fine but if we try to access the application through NLB IP address as http://1.2.3.3:80/example we are unable to access the application.

 

We have not done any special configuration in httpd.conf files of Apache 1 & 2 for NLB.

 

Please some one let me know why we are unable to access the application.

 

Is there any special configuration must be done in apache for achieving these.

 

Thanks

Vinay
