We have 3 domains in play here. Domain1.com is the main site, domain2.com is the smaller second site, and domain3.com is a vanity URL that redirects from domain1 to a Spanish version of domain2.
What we need to have happen is for domain3.com/subpage to redirect to domain2.com/subpage, however the original redirect of the vanity URL is overriding any attempts we make.
Is this kind of redirect possible?
Here is the original redirect in domain1.com's htaccess file:
RewriteCond %{HTTP:Host} ^www\.domain3\.com$
RewriteRule (.*) http\://www\.domain2\.com/spanish-version [I,R]
These are the attempts at making the needed redirect happen (also in domain1.com's htaccess file):
RewriteCond %{HTTP:Host} ^www\.domain3\.com/subpage$
RewriteRule (.*) http\://www\.domain2\.com/spanish-version/subpage [I,R]
RewriteRule ^domain3\.com/subpage?$ /spanish-version/subpage [NC,R=302,U]
