Client implementations are able to use CONNECT when requesting HTTP 
through a proxy but the major implementations choose not to do so.
Changing this behaviour is probably inadvisable as current proxies will 
most likely simply drop the connection when getting a CONNECT message 
for HTTP page.

And while the feature is most useful for CONNECT with HTTPS, and while 
it is likely that some proxies will continue to prefer ‘branded’ 
HTML pages, allowing the use of this answer on non CONNECT request may 
also hold value as promoting homogeneity to the user experience between 
HTTP and HTTPS.
