    Rewrite query string

    + + +
    +
    Description:
    +
    You want to capture a particular value from a query string +and either replace it or incorporate it into another component +of the URL.
    + +
    Solutions:
    +
    +

    Many of the solutions in this section will all use the same condition, +which leaves the matched value in the %2 backreference. %1 is the beginining +of the query string (up to the key of intererest), and %3 is the remainder. This +condition is a bit complex for flexibility and to avoid double '&&' in the +substitutions.

    +
      +
    • This solution removes the matching key and value: + +
      # Remove mykey=???
+RewriteCond %{QUERY_STRING} (.*(?:^|&))mykey=([^&]*)&?(.*)&?$
+RewriteRule (.*) $1?%1%3
      + +
      • + +
    • This solution uses the captured value in the URL subsitution, + discarding the rest of the original query by appending a '?': + +
      # Copy from query string to PATH_INFO
+RewriteCond %{QUERY_STRING} (.*(?:^|&))mykey=([^&]*)&?(.*)&?$
+RewriteRule (.*) $1/products/%2/? [PT]
      + +
      • + +
    • This solution checks the captured value in a subsequent condition: + +
      # Capture the value of mykey in the query string
+RewriteCond %{QUERY_STRING} (.*(?:^|&))mykey=([^&]*)&?(.*)&?$
+RewriteCond %2 !=not-so-secret-value 
+RewriteRule (.*) - [F]
      + +
      • + +
    • This solution shows the reverse of the previous ones, copying + path components (perhaps PATH_INFO) from the URL into the query string. +
      # The desired URL might be /products/kitchen-sink, and the script expects 
+# /path?products=kitchen-sink.
+RewriteRule ^/?path/([^/]+)/([^/]+) /path?$1=$2 [PT]
