How to cancel an MSXML2.XMLHTTP Request?

[Michael Posthoff]

Hello,

I load flightdetails as XML from various AirlineServers, that can take a
while, see the timeout from 120 secs in the code:

SET objHTTP = Server.CreateObject(Application("ServerXML"))
objHTTP.SetTimeouts 10000, 10000, 10000, 120000

objHTTP.open "POST", Application("XML_Requestor"), false
objHTTP.setRequestHeader "CONTENT-TYPE", "text/xml"
objHTTP.send XMessage


How can I cancel a request already sent, when, e.g. the client has already
canceled the connection, any ideas?

Regards,
Michael Posthoff

There is an abort method that can be called e.g.
objHTTP.abort
that cancels a request.

Hallo,

yes I am about to invoke it, but it demands the use of asynchronous calls
and the use of

objHTTP.onreadystatechange=checkState(objHTTP.readyState)

Causes the error..

If checkState is the name of a function then I think with VBScript you
need to assign
objHTTP.onreadystatechange = GetRef("checkState")
to set an event handler.
