With considerable help from this list years ago I wrote the below. It worked for a long time, until I upgraded emacs. It did what you want, plus a little bit more which can easily be edited out.

;url-fetch-web-page
;From within emacs, download & locally edit a remote web page.

;Using the url.el library, so probably need to load it.
(require 'url)

(defun url-fetch-web-page (url)
  "Retrieve minibuffer-specified web page, load into a new
buffer, then call another function for editing."
  (interactive "sLoad URL: ")
  (with-temp-buffer
    (url-retrieve url 'edit-web-page
    (list url 'status))))

(defun edit-web-page (&optional redirect url status)
      "Switch to the buffer returned by `url-retrieve'.
Automatically strip out all C-m characters and then insert after
html body tag the buffer's URL, appropriately html-tagged."
      (switch-to-buffer (current-buffer))
      ;; remove all instances of ^M (found in MS-created files).
      (goto-char 0)
      (perform-replace "
" "" nil nil nil t nil nil nil)
      (let ((case-fold-search t)) ;case-insensitive search
 (goto-char 0)   ;go to top of buffer
 (re-search-forward "<[\t\n ]*BODY[^>]*>" nil t)
 )
     ;insert URL into page
      (insert "\n\n<p>From: <a href=\""
       url "\">" url "</a>\n </p>\n\n"))
