Beta version of site via mod_rewrite

[imforumman]

I have two sub-domains pointing at the same directory.

When requesting a file via the "www" subdomain it should just deliver it.

When requesting a file via the "beta" subdomain it should check to see if the file exists at "/~beta/", and use that if it exists. Otherwise it should serve the same file as if it had been accessed via "www".

This must be done in such a way that if "beta.domain.net/path/file.html" exists (meaning "www.domain.net/~beta/path/file.html" exists) but a css file requested via relative paths used by that html file, does not exist, then it defaults back to the "www" version.

I can point the subdomain anywhere you want me to, speak I can point it at "/~beta/" if you that makes more sense.

Now my first crack at this looked like this:

Code: Select all

RewriteBase /
RewriteCond %{HTTP_HOST} ^beta.* # if on beta
RewriteCond /~beta%{REQUEST_FILENAME} -s # andif file exists in beta dir
RewriteRule ^(.*) /~beta$1 # rewrite!

or

Code: Select all

RewriteBase /
RewriteCond %{HTTP_HOST} ^beta.* # if on beta
RewriteRule ^(.*) /~beta$1 # rewrite!
RewriteCond %{REQUEST_FILENAME} !-s # if file does not exist
RewriteRule ^/~beta(.*) $1 # rewrite back

neither works at all. Please help me!

Thank you very much!

Check that HTTP_HOST is right. I have a feeling it may be different from the Host: header the visitor requested something like server.yourwebhost.com try %{HTTP:Host}

This might work

Code: Select all

RewriteBase /
RewriteCond %{HTTP:Host} ^beta\. # if on beta
RewriteCond %{DOCUMENT_ROOT}/~beta%{REQUEST_URI} -s # and if file exists in beta dir
RewriteRule ^ /~beta$1 # rewrite!

This might work

%{DOCUMENT_ROOT} contains /var/www/htdocs
%{REQUEST_URI} contains /var/www/htdocs/requested.php

If not (%{REQUEST_URI} contains only requested.php), there is an error in the server configuration.

BTW: Comments are not allowed this way, they must be in a separate line (otherwise you get a 500 internal server error)

Code: Select all

# comment
RewriteRule ....

This might work

%{REQUEST_URI} contains /var/www/htdocs/requested.php

Isn't that REQUEST_FILENAME. REQUEST_URI is supposed to contain basically what the visitor sent in the "GET <uri> HTTP/1.1" header.

yes, sorry I ment request_filename, which was used in posting #1;

according to a posting on modrewrite.de, the problem is now solved.
