Apparantly Microsoft (in for example IIS and IE) has a special HTTP status (449, HTTP_STATUS_RETRY_WITH) to "Retry after doing the appropriate action". I've only found very few web references to usage of this feature:

http://www.microsoft.com/windows2000/en/server/iis/htm/asp/eadg6isz.htm

http://msexchangeteam.com/archive/2005/07/07/407416.aspx

http://msexchangeteam.com/archive/2005/06/20/406586.aspx

Does anyone know more about this feature?

Does anyone know what the content of the 449 reply looks like? Maybe someone even can provide packet dumps?

No one knows anything about this?

Sorry, first I've heard of it.

If you want a thing well done, do it yourself... :-) This is the reply from IIS when I followed the instructions on http://www.microsoft.com/windows2000/en/server/iis/htm/asp/eadg6isz.htm. The "ms-echo-request" header certainly at work here. ----- 8< ----- HTTP/1.1 449 Retry with Server: Microsoft-IIS/5.1 Date: Fri, 28 Jul 2006 15:36:17 GMT Connection: close Content-Type: text/html ms-echo-request: execute opaque="0" location="BODY" Content-Length: 745 <HTML> <HEAD> <SCRIPT language="JavaScript"> function stopAllErrors() { // No errors should be presented to the user if they occur. return true; } window.onerror = stopAllErrors; function window.onload () { oClientCaps.style.behavior = "url(#default#clientCaps)"; bcString = "width= " + oClientCaps.width; bcString += "&height= " + oClientCaps.height; bcString += "&bufferDepth= " + oClientCaps.bufferDepth; bcString += "&colorDepth= " + oClientCaps.colorDepth; bcString += "&cookies= " + oClientCaps.cookieEnabled; bcString += "&platform= " + oClientCaps.platform; document.cookie = "BrowsCap= " + bcString; } </SCRIPT> </HEAD> <BODY ID="oClientCaps"> </BODY> </HTML> ----- 8< ----- When the client has processed the above reply, it sends a new request.
