示例1: doResponseRedirectOrNotModifiedLogic
protected boolean doResponseRedirectOrNotModifiedLogic(HttpServletRequest servletRequest, HttpServletResponse servletResponse,
HttpResponse proxyResponse, int statusCode) throws ServletException, IOException {
// Check if the proxy response is a redirect
// The following code is adapted from org.tigris.noodle.filters.CheckForRedirect
if (statusCode >= HttpServletResponse.SC_MULTIPLE_CHOICES /* 300 */
&& statusCode < HttpServletResponse.SC_NOT_MODIFIED /* 304 */) {
Header locationHeader = proxyResponse.getLastHeader(HttpHeaders.LOCATION);
if (locationHeader == null) {
throw new ServletException(
"Received status code: " + statusCode + " but no " + HttpHeaders.LOCATION + " header was found in the response");
}
// Modify the redirect to go to this proxy servlet rather that the proxied host
String locStr = rewriteUrlFromResponse(servletRequest, locationHeader.getValue());
servletResponse.sendRedirect(locStr);
return true;
}
// 304 needs special handling. See:
// http://www.ics.uci.edu/pub/ietf/http/rfc1945.html#Code304
// We get a 304 whenever passed an 'If-Modified-Since'
// header and the data on disk has not changed; server
// responds w/ a 304 saying I'm not going to send the
// body because the file has not changed.

servletResponse.setIntHeader(HttpHeaders.CONTENT_LENGTH, 0);
servletResponse.setStatus(HttpServletResponse.SC_NOT_MODIFIED);
return true;
}
return false;
