Directives

• ProxyPass
• ProxyIOBufferSize

Forward Proxy Configuration

A forward proxy is activated using the ProxyRequests directive.

Reverse Proxy Configuration

A reverse proxy is activated using the ProxyPass directive or the [P] flag to the RewriteRule directive. It is not necessary to turn ProxyRequests on in order to configure a reverse proxy.

Controlling access to the Proxy

Use the <Proxy> control block:

<Proxy "*">
    Require ip 192.168.0
</Proxy>

mod_proxy mod_cluster Configuration

mod_proxy directives like ProxyIOBufferSize could be used to configure mod_cluster.

There is no need to use ProxyPass directives because mod_cluster automatically configures which URLs have to be forwarded to JBossWEB.

Reference

ProxyTimeout

This directive allows a user to specifiy a timeout on proxy requests. This is useful when the application server is slow, and you would rather just return a timeout and fail gracefully instead of waiting however long it takes the server to return.
