title: How to change the root context for the Web module in the IHS+WAS configuration?
body: <p>I have following configuration:</p>
  
  <ul>
  <li>Websphere ND 8.0 with some deployed applications;</li>
  <li>IHS (IBM HTTP Server) 8.0;</li>
  <li>Web Server Plug-ins 8.0;</li>
  </ul>
  
  <p>All of the deployed applications has some unique root context. What I need is to change this root context for some of them.
  For example I have a following link - <code>http//host:port/app1/index.jsp</code>, where app1 is a root context. I need to make it work through the following link <code>http//host:port/cust/app1/index.jsp</code>. (it would be better if the old link doesn't work after such modification).</p>
  
  <p>I've tried to reach this without the IHS layer. WAS do allows to change the root context, and this is pretty easy. The problem is that the deployed apps use direct mapping to the root context within their internal resources. (i.e. some app1's resources, like JS, HTML..., contains direct pointing to the /app1/...). In this case simple changing of the root context is not suitable. I need to change all such internal resources manually. I know that this is the poor implementation but that is what I have. This solution is definitely not the best, but at least it works.</p>
  
  <p>I need to do the same thing (well, not the same. the result should be the same) but now with the IHS.
  I'm not familiar with the IHS installation\configuration. Here is my understanding of how does it works:</p>
  
  <p>Client->IHS->WAS(applications)</p>
  
  <p>IHS communicated with the WAS through the <strong>mod_was_ap22_http</strong> plugin, where the <strong>plugin-cfg.xml</strong> shows the URL templates to be processed. (don't know how exactly does it works)</p>
  
  <p>*Basically Clent send following request - <code>http//IHS_host:port/app1/index.jsp</code>.</p>
  
  <p>*IHS start process that request through the mod_was_ap22_http.</p>
  
  <p>*If the request match to the plugin-cfg.xml rules then it goes to the WAS.</p>
  
  <p>All this time the root context was the <strong>app1</strong>.
  Is it possible to configure IHS to change the original root context, and make that the Client works through the new root context only? As the result user should not see the <code>http//IHS_host:port/app1/*</code>, he should see only <code>http//IHS_host:port/cust/app1/*</code></p>
