The solution I came up with involved making customized versions of
`gnus-article-browse-html-article` and `gnus-article-browse-html-parts`,
which I called `gnus-article-browse-remote-html-article` and
`gnus-article-browse-remote-html-parts`, respectively.  The changes were minor.

The only change in `gnus-article-browse-remote-html-article` is that it
calls `gnus-article-browse-remote-html-parts` instead of
`gnus-article-browse-html-parts`.  In `gnus-article-browse-remote-html-parts`, 
the line 

(let (type file charset content cid-dir tmp-file showed)

changes to

(let (type file charset content cid-dir tmp-file showed
(temporary-file-directory "/www/tmp") )

and after 

(setq tmp-file (mm-make-temp-file
                ;; Do we need to care for 8.3 filenames?
                "mm-" nil ".html")) 

I added the line

(set-file-modes tmp-file #o644)).

Finally

(browse-url-of-file (or tmp-file (expand-file-name file)))

changes to

(browse-url-of-file (concat "http://"; system-name (replace-regexp-in-string 
"/www" "" tmp-file)))

but this may vary depending on your web server configuration.
