301 redirect from mod_rewrite RewriteMap program
I'm using mod_rewrite's RewriteMap directive to process URLs. My RewriteMap program is a PHP script and everything is running fine. I'm开发者_开发技巧 able to map friendly URLs to PHP program + ID. Anyway, what I want to do is return a 301 redirect for certain URLs. For example, if someone puts in the URL:
http://www.example.com/directory1
Then I want my RewriteMap program to send a 301 redirect to
http://www.example.com/directory1/
(trailing slash)
Which will then go into my program again to be mapped onto a PHP script. I tried adding [R=301] at the end of my statement, but this just hangs the request. Here's the basic logic of my script:
if ($input_url == "/directory1") { echo "/directory1/ [R=301]\n"; // this doesn't work... just hangs } else if ($input_url == "/directory1/") { echo "/myprogram.php?id=1\n"; }
Any ideas?
The -d test in RewriteCond is designed specifically for your case Sridhar. It tests if there is a directory present in the filesystem. If true, AND if there is no trailing slash, then you could apply the redirect. That would be like this:
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule .*[^/]$ %{REQUEST_URI}/ [L,R=301]
You wouldn't need a RewriteMap (prg) in this case.
That’s not possible the way you want to do it. But you could use an additional rule to redirect all requests of URLs without a trailing slash:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule .*[^/]$ %{REQUEST_URI}/ [L,R=301]
