Fielding, et.al., 1997 </font> <p> This class of status code indicates that further action needs to be taken by the user agent in order to fulfill the request. The action required MAY be carried out by the user agent without interaction with the user. <!-- if and only if the method used in the second request is GET or HEAD. A client SHOULD detect infinite redirection loops, since such loops generate network traffic for each redirection.--> <blockquote> <a href="status1xx.html">1xx - Information</a><br> <a href="status2xx.html">2xx - Success</a><br> <a href="#300">300 - Multiple Choices</a><br> <a href="#301">301 - Moved Permanently</a><br> <a href="#302">302 - Found</a><br> <a href="#303">303 - See Other</a><br> <a href="#304">304 - Not Modified</a><br> <a href="#305">305 - Use Proxy</a><br> <a href="#306">306 - (Unused)</a><br> <a href="#307">307 - Temporary Redirect</a><br> <a href="status4xx.html">4xx - Client Error</a><br> <a href="status5xx.html">5xx - Server Error</a> </blockquote> <a name="300"> <p><b>300 Multiple Choices</b> </a> <p> The requested resource corresponds to any one of a set of representations, each with its own specific location, and agent- driven negotiation information <!-- (section 12) --> is being provided so that the user (or user agent) can select a preferred representation and redirect its request to that location. <p> Unless it was a HEAD request, the response SHOULD include an entity containing a list of resource characteristics and location(s) from which the user or user agent can choose the one most appropriate. The entity format is specified by the media type given in the Content- Type header field. Depending upon the format and the capabilities of the user agent, selection of the most appropriate choice MAY be performed automatically. However, this specification does not define any standard for such automatic selection. <a name="301"> <p><b>301 Moved Permanently</b> </a> <p> The requested resource has been assigned a new permanent URI and any future references to this resource SHOULD use one of the returned URIs. Clients with link editing capabilities ought to automatically re-link references to the Request-URI to one or more of the new references returned by the server, where possible. This response is cacheable unless indicated otherwise. <p> The new permanent URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s). <p> If the 301 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued. <a name="302"> <p><b>302 Found</b> </a> <p> The requested resource resides temporarily under a different URI. Since the redirection might be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. This response is only cacheable if indicated by a Cache-Control or Expires header field. <p> The temporary URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s). <p> If the 302 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued. <a name="303"> <p><b>303 See Other</b> </a> <p> The response to the request can be found under a different URI and SHOULD be retrieved using a GET method on that resource. This method exists primarily to allow the output of a POST-activated script to redirect the user agent to a selected resource. The new URI is not a substitute reference for the originally requested resource. The 303 response MUST NOT be cached, but the response to the second (redirected) request might be cacheable. <p> The different URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s). <a name="304"> <p><b>304 Not Modified</b> </a> <p> If the client has performed a conditional GET request and access is allowed, but the document has not been modified, the server SHOULD respond with this status code. The 304 response MUST NOT contain a message-body, and thus is always terminated by the first empty line after the header fields. <a name="305"> <p><b>305 Use Proxy</b> </a> <p> The requested resource MUST be accessed through the proxy given by the Location field. The Location field gives the URI of the proxy. The recipient is expected to repeat this single request via the proxy. 305 responses MUST only be generated by origin servers. <a name="306"> <p><b>306 (Unused)</b> </a> <p> The 306 status code was used in a previous version of the specification, is no longer used, and the code is reserved. <a name="307"> <p><b>307 Temporary Redirect</b> </a> <p> The requested resource resides temporarily under a different URI. Since the redirection MAY be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. This response is only cacheable if indicated by a Cache-Control or Expires header field. <p><hr size="2" width="85%" align="left" noshade><br> </body> </html>
