bug#35969: 26.2, Excorporate

From: tenspd137 .
Subject: bug#35969: 26.2, Excorporate
Date: Fri, 14 Jun 2019 17:14:26 -0600 
Sorry - I was working fast:

*I created a function that changed the line
in  url-http-create-request so that the request looks like:*

In a file I did:

(defun thefile() "/EWS/Exchange.asmx")

(copied from url-http library)
(defun url-http-create-request (&optional ref-url)
.....
   ;; This was done with a call to `format'.  Concatenating parts has
    ;; the advantage of keeping the parts of each header together and
    ;; allows us to elide null lines directly, at the cost of making
    ;; the layout less clear.
    (setq request
          (concat
             ;; The request
             (or url-http-method "GET") " "
             (url-http--encode-string
              (if using-proxy (thefile) real-fname))
<------------Changed this to "hardcode" the request as proof of
concept
             " HTTP/" url-http-version "\r\n"
             ;; Version of MIME we speak
             "MIME-Version: 1.0\r\n"
             ;; (maybe) Try to keep the connection open
             "Connection: " (if (or using-proxy .....
.......
.......

Loaded the file and then ran (url-retriev-synchronously "https://......";)

Thanks!
