Inverse proxy breaks permalinks

[Bernhard Reiter]

I have a WP installation at my university's webspace (on an apache server), say ​http://myuni.ac.at/mydir/wordpress/ , and an inverse proxy domain ​http://mydomain.at/ for it.
This means that any request to the latter, eg for ​http://mydomain.at/2009/02/12/inverse-proxy-trouble/ , is forwarded to ​http://myuni.ac.at/mydir/wordpress/ , which in turn means that the REQUEST_URI there becomes /mydir/wordpress/2009/02/inverse-proxy-trouble/ . My home variable is of course set to ​http://mydomain.at/ (siteurl is set to ​http://myuni.ac.at/mydir/wordpress/ -- otherwise I wouldn't be able to login to WP).

Unfortunately, when analyzing REQUEST_URI, wordpress chops off the home path, not the siteurl one. This may be okay for some purposes, but in the inverse proxy case, permalinks break. For a fix, I had to hack two wordpress core files, namely

wp-includes/classes.php
in function parse_request: change line 162 from

$home_path = parse_url(get_option('home'));

to

$home_path = parse_url(get_option('siteurl'));

and wp-includes/rewrite.php, in function get_pagenum_link, line 987, same modification.

This is a dirty hack, of course; so I wonder if in general, using the siteurl path is valid in any case where the home host differs from the siteurl host. If so, I suggest changing the affected files in such a manner.

please be so kind to give the attached patch a try

[Denis-de-Bernardy]

this might be a bit too big a change for a nearby release.

[Denis-de-Bernardy]

no tests in 2 weeks, punting to 2.9

Punting to Future Release due to no traction.

Still needs unit tests and a refresh

Considering that it needs a refresh according to @chriscct7 and no changes have occurred since then, I'm removing the Needs Testing tag, as there is nothing to test here.

This has had basically no movement in 17 years. I'm making an executive decision to close it. Thanks everyone.

You have closed Bernhard first ticket. That is the real executivity.
