如何使用 htaccess 阻止 url 的一部分？

Question

So basically, I have a link looking like:

mydomain.com/file.php?id=m03u7dp255jiobi&type=mp3

How do I block access to this URL only for this ?id= part

So when users visit this link file.php?id=test it won't work, but if they visit the other link looking like this ?id=validurl it will work.

.htaccess

To do this in .htaccess you can use the mod_rewrite module and set conditions against the query string.

ReWriteCond %{QUERY_STRING} id=invalid_string [OR]
ReWriteCond %{QUERY_STRING} id=another_invalid_string
ReWriteRule . /new_destination.php [QSD,L,R=307]

• OR - Literally an OR operator; as in Condition1 || Condition 2 Condition1 || Condition 2
• QSD - Removes the original query string
• L - Stops further rewrite rules from being applied
• R=307 - Sets a 307 Temporary Redirect status code
  • R=401 Sets an Unauthorised status code and redirects automatically to a predefined 401 resource ( ErrorDocument )

    • You can custom set the ErrorDocuments like:

       ErrorDocument 401 /errors/unauthorised.php
