QUERY_STRING
The information which follows the ? in the URL which referenced this script. This is the query information. It should not be decoded in any fashion. This variable should always be set when there is query information, regardless of command line decoding.
Query_String_Decoded
Returns the same as Query_String, but decodes the string. For example, if a URL references a view name that contains characters that are not allowed in a URL, the name is encoded. This CGI variable decodes that string. Path_Info_Decoded is available to Domino applications only.
