Apache Rewrite Rule on Dispatcher - apache

Question

How can I do a rewrite rule for both http://domain/abc to rewite/redirect to http://domain/abc.html but it should work when I have url as http://domain/abc/def.html. Currently when I do redirect 301 "abc" "abc.hml" the second url is also redirecting to http://domain/abc.html/def.html.
My current rules.
<IfModule rewrite_module>
RewriteEngine On
RewriteRule ^/$ /content/aaa-123/abc.html [PT,L]
RewriteRule ^/index.html$ /content/aaa-123/abc.html [PT,L]
RedirectMatch ^/abc$ /abc.html
RewriteCond %{REQUEST_URI} !^/(.*)/$
RewriteCond %{REQUEST_URI} !^(.*)\.(.*)$
RewriteRule ^/(.*)$ /content/$1/ [L]
RewriteRule \.(css|jpe?g|gif|png|js)$ - [L]
ErrorDocument 404 /errors/404.html
<IfModule mod_expires.c>
ExpiresActive on
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType text/html "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType text/css "access plus 1 year"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 1 month"
</IfModule>
<IfModule mod_headers.c>
<FilesMatch "\.(js|css|xml|gz)$">
Header append Vary: Accept-Encoding
</FilesMatch>
</IfModule>
Thanks

Answer 1

Use RedirectMatch instead of Redirect to match using regular expressions:
Options -MultiViews
RewriteEngine On
RewriteRule ^/abc/?$ /abc.html [NC,L,R=302]
RewriteRule \.(css|jpe?g|gif|png|js)$ - [L,NC]
RewriteRule ^/(index\.html)?$ /content/aaa-123/abc.html [PT,L,NC]
RewriteCond %{REQUEST_URI} !^/(.*)/$
RewriteCond %{REQUEST_URI} !^(.*)\.(.*)$
RewriteRule ^/(.*)$ /content/$1/ [L]
Clear your browser cache before testing this rule and do restart Apache after making these changes.

For the first you could use this:
RedirectMatch ^/abc$ /abc.html
This tells apache to redirect only "/abc"
Although it sounds as you want MULTIVIEWS in Apache. Multiviews is an Option with which Apache will examine a request and add an extension if it finds a file matching the request, so if you request abc and there is abc.html it will load it.
