In /home/y/conf/yts/plugin.config, you can add
  1) custom_redirect.so
  or
  2) custom_redirect.so wretch-redirect-url
  or
  3) custom_redirect.so 507

Case 1) means using the default header (x-redirect-url) to specify a URL to redirect to;
Case 2) user specifies their specific header name (to replace the default one) to specify a URL to redirect to;
Case 3) user sepcifies the specific return code, if return code matches, then plugin will force to redirect to the
URL specified in standard "Location" header.

For simplicity, we recommend to use case 1)

This is a plugin for YTS (Yahoo Traffic Server) that allows OS (Origin Server)
to do either of the following two things:

  1) specify a particular response header (default: x-redirect-url) with a URL
     that forces YTS redirect to that URL;

  2) specify a particular return error code (such as 507) with a standard Location
     header which forces YTS to redirect to that location URL.

Version 0.1 (09/17/09, wenjing)
