I have a Wordpress multisite configuration like this:

  • www.domain.com/ -> Primary site (not used)
  • www.domain.com/de-de/ -> German site
  • www.domain.com/en-us/ -> English site

However, for reasons unrelated to Wordpress, I need that the network sites have this layout:

  • www.domain.com/de-de/blog/ -> German site
  • www.domain.com/en-us/blog/ -> English site

Unfortunately, you cannot define a site as de-de/blog in your WP network because the forward slash is not an allowed character for a site name.

Therefore, I tried defining a reverse proxy like this on Apache:

ProxyPreserveHost On
ProxyPass        "/de-de/blog/" ""
ProxyPassReverse "/de-de/blog/" ""
ProxyPass        "/en-us/blog/" ""
ProxyPassReverse "/en-us/blog/" ""

This seems to do the trick for site routing, but in the returned page, the internal URLs in the HTML page are www.domain.com/de-de/, not www.domain.com/de-de/blog/

How could I have WP in multisite mode use URL layout from upstream (i.e. www.domain.com/de-de/blog/) in the rendered HTML pages?

I fixed it changing the urls of the sites to include the /blog/ suffix. You cannot create the site with a slash but you can change the site URL once it is created.

Then changing the RewriteRules in .htaccess to:

RewriteRule ^([_0-9a-zA-Z-]+/blog/)?wp-admin$ $1wp-admin/ [R=301,L]
RewriteRule ^([_0-9a-zA-Z-]+/blog/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/blog/)?(.*\.php)$ $2 [L]

Finally, adding some code to wp-config.php to properly define the PATH_CURRENT_SITE and BLOG_ID_CURRENT_SITE variables:

define('PATH_CURRENT_SITE', $path_current_site);
define('BLOG_ID_CURRENT_SITE', $blog_id_current_site);
