Mod rewrite base URL

Question

I have several domains that I want to all rewrite to one domain. I don't want it to redirect because I want the URL to look like what the user has entered in. For example if they enter www.example.com I want it to load the page from www.sample.com/default.php?from=example

I have worked a little with rewriting if you have www.site.com/var1/var2 making it load www.site.com/index.php?one=var1&two=var2

Is it possible to do what I am looking for just through the .htaccess file? I tried looking around and couldn't exactly find what I was looking for

Thanks

If the sites are hosted on different servers or don't share a common document root, then you'll have to rely on mod_proxy and you can use the P rewrite rule flag. For example, these rules in an htaccess file in www.example.com 's document root:

RewriteCond %{HTTP_HOST} ([^.]+)\.com$ [NC]
RewriteRule ^/?$ http://www.sample.com/default.php?from=%1 [L,P]

Will take the request http://www.example.com/ and invisibly proxy it to http://www.sample.com/default.php?from=example . The browser's URL address bar will remain http://www.example.com/ .

Note that the rule only matches against the request URI / . If you want to do more, you'd have to create the correct regular expression and grouping.

If you have redirects on the sample.com site, you'll need to employ ProxyPassReverse to rewrite the redirects. Also see ProxyPassReverseCookieDomain and ProxyPassReverseCookiePath if there are cookies involved.

If you can do this in vhost or server config instead, then consider simply using ProxyPass instead of mod_rewrite. The ProxyPass directive won't work inside htaccess files.

EDIT:

Seeing as how everything is in the same document root, you won't need to proxy anything. Simply:

RewriteCond %{HTTP_HOST} !^www\.sample\.com$ [NC]
RewriteCond %{HTTP_HOST} ([^.]+)\.com$ [NC]
RewriteRule ^/?$ /default.php?from=%1 [L]

I use online generators. Use this generator: mod-rewrite
