doc:

javax.servlet.http
Interface HttpServletRequest

getRequestURL

public java.lang.StringBuffer getRequestURL()

Reconstructs the URL the client used to make the request. The returned URL contains a protocol, server name, port number, and server path, but it does not include query string parameters.

Because this method returns a StringBuffer, not a string, you can modify the URL easily, for example, to append query parameters.

This method is useful for creating redirect messages and for reporting errors.

Returns:

a StringBuffer object containing the reconstructed URL

Ahoj,
mám URL třeba http://www.adresa.cz/view/test a potřeboval bych ho nějak změnit na http://www.adresa.cz/view?show=test. Jak se to dá udělat? Pomocí servlet filtrů?
