ErrorServlet (Top level OA4MP 5.3-SNAPSHOT API)

java.lang.Object
- javax.servlet.GenericServlet
- - javax.servlet.http.HttpServlet
  - - edu.uiuc.ncsa.security.servlet.AbstractServlet
    - - edu.uiuc.ncsa.myproxy.oa4mp.server.servlet.EnvServlet
      - edu.uiuc.ncsa.myproxy.oa4mp.server.servlet.MyProxyDelegationServlet
        
        edu.uiuc.ncsa.myproxy.oa4mp.server.servlet.ErrorServlet

All Implemented Interfaces:

TransactionFilter, edu.uiuc.ncsa.security.core.Logable, Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
```
public class ErrorServlet
extends MyProxyDelegationServlet
```
This servlet handles error redirects. If an error (such as a 404, 500 or anything else) occurs, OAuth will intecept the response and throw an exception -- losing any other information. Therefore, there must be a redirect and clients must be prepared to deal with these. Generally there are a few error type pages
