Rewriting rules configuration

Rewriting rules define how the proxy server rewrites URLs. Responses that have been redirected by target servers typically return a 302 status code with a location header that defines the URL that the client should be redirected to. Rewriting this URL is necessary if the target server is not aware of the proxy servers. The redirected URL is modified to correctly point clients to the proxy server instead of directly to a target server that may not be visible to clients. Use the following properties to configure the URL rewriting rules for a proxy server

The proxy server only supports rewriting redirected responses. Therefore, these the following settings only apply to redirected responses. These settings do not apply to requests because the proxy server does not support URL rewriting for requests.gotcha To view this console page, click Servers > Server Types > WebSphere proxy servers > proxy_server_name > HTTP proxy server settings > Rewriting rules > New.
