Forward vs Redirect in servlet

Forward vs Redirect in servlet

 Forward

    * a forward is performed internally by the servlet
    * the browser is completely unaware that it has taken place, so its original URL remains intact
    * any browser reload of the resulting page will simple repeat the original request, with the original URL

Redirect

    * a redirect is a two step process, where the web application instructs the browser to fetch a second URL, which differs from the original
    * a browser reload of the second URL will not repeat the original request, but will rather fetch the second URL
    * redirect is marginally slower than a forward, since it requires two browser requests, not one
    * objects placed in the original request scope are not available to the second request
