Hi! I'm trying to get my head around RewriteCond, and want to rewrite any requests either to a static html page (if it exists), or to a specific index.php (so long as the requested file doesn't exist).

To illustrate the logic:

if HTTP_HOST is '(www\.)?mydomain.com'
    if file exists: "/default/static/{REQUEST_URI}.html", then
        rewrite .* to /default/static/{REQUEST_URI}.html
    else if file exists: {REQUEST_FILENAME}, then
        do not rewrite
    else
        rewrite .* to /default/index.php

I don't seem to have much trouble doing it when I don't need to test for the HTTP_HOST. Ultimately, this one .htaccess file will be handling requests for several domains.

I know I could get around this with vhosts, but I'd like to figure out how to do it this way.

Here's where I am at now:

RewriteCond %{HTTP_HOST} ^(www\.)?mydomain\.com$    [NC]

RewriteCond /default/static/%{REQUEST_URI}.html -f
RewriteRule . /default/static/%{REQUEST_URI}.html   [L,NC]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule . /default/index.php            [L,QSA]

I'm not too familiar with some of the other flags, will any of them be of use here (like chain|C, next|N or skip|S)?

Thanks in advance!

UPDATE: I've managed to do it, but would appreciate alternatives:

RewriteEngine On
RewriteRule ^(.+)/$  /$1 [L]

RewriteCond %{HTTP_HOST} ^(domainA|domainB)\.com        [NC]
RewriteCond %{DOCUMENT_ROOT}/%1/static/%{REQUEST_URI}.html -f
RewriteRule (.*)? /%1/static/$1.html            [NC,L]

RewriteCond %{HTTP_HOST} ^(domainA|domainB)\.com        [NC]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .* /%1/index.php                [L,QSA]
