Apache rewrite rule - regex help

I have 7 urls:

url: /v/3b89441db7986135e5eb9e1debf0cc23
url: /v/3b89441db7986135e5eb9e1debf0cc23/login
url: /v/3b89441db7986135e5eb9e1debf0cc23/logout
url: /v/3b89441db7986135e5eb开发者_如何转开发9e1debf0cc23/access
url: /v/3b89441db7986135e5eb9e1debf0cc23/delete-attendee/:id
url: /v/3b89441db7986135e5eb9e1debf0cc23/edit-attendee/:id
url: /v/3b89441db7986135e5eb9e1debf0cc23/finalise

How could I write a rewrite rule that if these URLS are not matched, I redirect the user to another domain?

For example the part after /v/ is always a 32 character MD5 string. the :id part is always a number.

If you could give me a regex (regex has alas never been my forte) example for

/v/3b89441db7986135e5eb9e1debf0cc23

and

/v/3b89441db7986135e5eb9e1debf0cc23/edit-attendee/:id

that would be excellent.

This regex matches your urls:

/v/[a-f0-9]{32}(/[a-z-]+(/\d+)?)?

In english...

• /v/ is a literal
• [a-f0-9]{32} means 32 hex digits
• /[a-z-]+(/\d+)? means "/" then at least 1 of (any lowercase letter or a dash) then "/" then some digits
• surrounding a regex in (...)? means either one or none of them

FYI, this regex matches all urls given in question reasonably tightly

If you want to not match, use this:

^(?!/v/[a-f0-9]{32}(/[a-z-]+(/\d+)?)?$)

---

How about this:

\/v\/[a-f0-9]{32}(\/(login|logout|access|delete-attendee\/:\d+|edit-attendee\/:\d+|finalise)?

This will only match your accepted urls. You should adjust for your flavor or regex and appropriate escape chars.

---

You said that you want to redirect if URLs do not match, so first you must make a rule that matches all valid URLs, then prepend ! to negate the match.

RewriteEngine On
RewriteRule !^v/[0-9a-f]{32}(/(login|logout|access|delete-attendee/\d+|edit-attendee/\d+|finalise))?$ http://your-other-domain/ [R]

The above rule should be placed in the .htaccess file present in the root directory of your website.
