Proxy Server allows PURGE requests to clear the cached URL. If the requested URL is purged successfully, a response with an HTTP status code of 200 (OK) is sent by the server. If the specified URL is not cached, a 404 (Not Found) response is sent.
In the following example, the server returns the value 200
bash-2.03$ telnet localhost 8088 Trying 172.9.10.1... Connected to localhost. Escape character is '^]'. PURGE http://foo.com/ HTTP/1.0 HTTP/1.1 200 OK Server: Sun-Java-System-Web-Proxy-Server/4.0 Date: Fri, 26 Oct 2007 08:15:30 GMT Connection: close
In the following example, the server returns the value 404.
Connection closed by foreign host. bash-2.03$ telnet localhost 8088 Trying 172.9.10.1... Connected to localhost. Escape character is '^]'.
