getSourceURL

public static URL getSourceURL(javax.servlet.http.HttpServletRequest servletRequest)

Try to extract from various http headers the URL (<protocol>://<host>[:<port>]/<path>[?<querystring>]) as close as possible to the one used by the client.

Parameters:

servletRequest - the servlet request input

Returns:

the URL as close as possible from what the client used

getSourceBaseURL
