see a 301 error in a Web browser, unless perhaps you have a corrupt redirection chain e.g. URL A 301 moved permanently nginx redirects to URL B which in turn redirects back to URL A. If your client is not a Web browser, it should behave in the same way as a Web 301 moved permanently curl browser i.e. immediately retry the alternative URL. If the Web server does not return an alternative URL with the 301 response, then either the Web server software itself is defective or the Webmaster has not set up the URL redirection correctly. Fixing 301 errors - CheckUpDown Redirection of URLs may occur for low-level URLs (specific URLs within the Web site such as
301 Moved Permanently Error
www.isp.com/products/index.html) when you reorganise the web site, but is relatively uncommon for top-level URLs (such as www.isp.com) which most users specify for their CheckUpDown accounts. So this error should be fairly infrequent. The 301 response from the Web server should always include an alternative URL to which redirection should occur. If it does, CheckUpDown automatically tries the alternative URL. This in turn may possibly lead to another redirection which CheckUpDown then tries. This continues for a maximum of 5 redirections. As soon as 5 redirections have occurred, CheckUpDown gives up and reports the 301 error for your account. So you should only ever see the 301 error if 1) the Web server gives no alternative URL on the 301 response or 2) the number of redirections exceeds 5. This second condition should be fairly unlikely - and may indicate a recursive pattern e.g. URL A redirects to URL B which in turn redirects back to URL A. You first need to check that the IP name we use to check for your account is accurate. If you or your ISP have con
response. 10.1 Informational 1xx This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. There http 301 vs 302 are no required headers for this class of status code. Since HTTP/1.0 did 301 moved permanently error fix not define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental

conditions. A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message. Unexpected http://www.checkupdown.com/status/E301.html 1xx status responses MAY be ignored by a user agent. Proxies MUST forward 1xx responses, unless the connection between the proxy and its client has been closed, or unless the proxy itself requested the generation of the 1xx response. (For example, if a proxy adds a "Expect: 100-continue" field when it forwards a request, then it need not forward the corresponding 100 (Continue) response(s).) https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html 10.1.1 100 Continue The client SHOULD continue with its request. This interim response is used to inform the client that the initial part of the request has been received and has not yet been rejected by the server. The client SHOULD continue by sending the remainder of the request or, if the request has already been completed, ignore this response. The server MUST send a final response after the request has been completed. See section 8.2.3 for detailed discussion of the use and handling of this status code. 10.1.2 101 Switching Protocols The server understands and is willing to comply with the client's request, via the Upgrade message header field (section 14.42), for a change in the application protocol being used on this connection. The server will switch protocols to those defined by the response's Upgrade header field immediately after the empty line which terminates the 101 response. The protocol SHOULD be switched only when it is advantageous to do so. For example, switching to a newer version of HTTP is advantageous over older versions, and switching to a real-time, synchronous protocol might be advantageous when delivering resources that use such fea
of 301 tells a client that the resource they asked for http://100pulse.com/http-statuscode/301.jsp has permanently moved to a new location. The response should http://www.somacon.com/p145.php also include this location. It tells the client to use the new URL the next time it wants to fetch the same resource. Why it Occurs If a client has link-editing capabilities, it should update all references to the 301 moved Request URL. The response is cacheable. Unless the request method was HEAD, the entity should contain a small hypertext note with a hyperlink to the new URL(s).If the 301 status code is received in response to a request of any type other than GET or HEAD, the client must ask 301 moved permanently the user before redirecting.

is used to indicate that a page has permanently moved. Multiple techniques are presented with recommendations. In order to redirect an out-of-print web page to another location, return the HTTP 301 status code and a location header in the HTTP response of the deprecated web page. The HTTP 301 response code will tell user-agents that the location has permanently moved. This is particularly useful for search engines like Google, which will carry over page rank to the new page if this status code is seen. If you do not need to indicate permanent displacement, you can accomplish redirection by setting a Location header in PHP or using Response.Redirect in ASP. The location header does the actual redirection to the new location, and can be used by itself. HTTP headers are sent for every web page. If you want to see what HTTP headers look like for a particular page, visit Rex Swain's HTTP Viewer. For advanced users, I would recommend you download the Firefox web browser and install Chris Pederick's Web Developer Extensions. Then, use the Information->View Response Headers function. In scripts, HTTP headers must be sent before sending any page content, including white space, or else an error will result. HTTP 301 Redirect in ASP-VBScript <%@ Language=VBScript %> <% ' Permanent redirection Response.Status = "301 Moved Permanently" Response.AddHeader "Location", "http://www.somacon.com/" Response.End %> In Active Server Pages (ASP), Response.Redirect does not work the same as the code shown in the example. Response.Redirect will set the location header as shown, but it will set the status code to HTTP/1.1 302 Object moved instead. When you set the Location header with Response.AddHeader, the status code must be manually defined, otherwise it stays 200 OK. If you send any page content prior to the headers, you will get an error like, "Response object error 'ASP 0156 : 80004005'; Header Error; The HTTP headers are already written to the client browser. Any HTTP header modifications must be made before writing page content.". Normally, you do not see this error even if there is content prior to the redirect, because page buffering is enabled by default in IIS. If you want to be sure there is no content being sent before the redirect, call Response.Flush just before it, disable page buffering with Response.Buffer = False, or configure IIS to disable page buffering. (Disabling buffering reduces performance.) HTTP 301 Redirect in PHP <
