We are sending 1k request xml files to a server and have been receiving the proper xml response files for some time now, but when we try to send request xml files larger than 2044 bytes in size the server people tell us they are receiving truncated request files.

We have tried using setrequestheader method as such:
loxml.setrequestheader("Content-Length",len(lcxml))
but this doesn't seem to change anything at all.
I notice that docs say that the 2nd parameter is of type bstr.
Could this have something to do with our failure here as we are passing a numeric value.

Has anyone found an object model for this component on the web?
