RE: VB6 MSXML2.XMLHTTP40 Error

Hi,
I've carefully reviewed your question. Here's my understanding so far, let
me know if I've misunderstood anything:
1) You have 5 servers and 5 websites on each server using the same IP, this
makes 25 websites;
2) You have a synchronous xmlhttp call to retrieve content from the
websites in VB6 using MSXML.
3) Once in a while, calling into one of your websites will cause
objXmlHttp.Send fail; and if you want to retry that again later, calling
..Open will cause error "This method cannot be called until the open method
has been called".
I've searched in our internal support database but didn't found any
relevant cases about such issue. Generally such non-reproducible issue is
difficult to solve completely in newsgroup. Anyway, here's some general
suggestion on where to look into:
1) Make sure the MSXML runtime is up-to-date.
(http://support.microsoft.com/kb/278674,
http://support.microsoft.com/kb/269238)
2) Check the web server log to see why the .send is failing first.
Sincerely,
Walter Wang (wawang@xxxxxxxxxxxxxxxxxxxx, remove 'online.')
