Thomas -
I was able to try stepping through an Emacs/proxy/Exchange test in an
emacs -Q session. After setting the proxy and configuring the
debugger to step through url-http and url-http-async-sentilnel, the
only thing I noticed is that it appears url-http-async-sentinel is not
being called. I also put the url-https-proxy-connect override you
gave me earlier into a file, loaded it and set the debugger to run
through that as well as set up proxies. A broken down list of steps:
1. Load file containing proxy and altered url-https-proxyconnect, set
debugger to run through it when hit.
2. set up url-http and url-http-async-sentinel to be picked up by debugger
3. eval (url-retrieve-synchronously
"https://outlook.office365.com/EWS/Exchange.asmx"), step through
url-http
4. Input username and password when asked
5. Continue stepping until end
url-http-async-sentinel is never called. " *http* ... -####" has text
indicating failure. url-https-proxy-connect is indeed called. I don't
know how to look at the actual <process>, if I try to C-x C-e or M-:
"connection", it goes into the debugger. The url's, etc look good as
far as I can tell. Not sure what else I can do. If there are certain
pieces of url-http you want me to look at, just let me know, but not
really knowing what has to happen under the hood, I am not going to be
able to do much else.
Thanks!
