Replacing a querystring parameter value using mod_rewrite
问题 I would like to map this: http://www.example.com/index.php?param1=value1¶m2=value2¶m3=value3 (etc. ad infinitum) to http://www.example.com/index.php?param1=newvalue1¶m2=value2¶m3=value3 (etc.) In other words, just change the value of a single parameter in the query string. I know what the old value is, so I am trying to match the exact text index.php?param1=value1 and replace it with index.php?param1=newvalue1 . I cannot seem to find any examples on how to do this using mod
