Path_Info	/w/dc.nsf/tag/ibm	The extra path information (from the server's root HMTL directory), as given by the client. In other words, scripts can be accessed by their virtual path name, followed by extra information that is sent as PATH_INFO.
Path_Info_Decoded	/w/dc.nsf/tag/ibm	Returns the same as Path_Info, but decodes the string. For example, if a URL references a view name that contains characters that are not allowed a URL, the name is encoded. This CGI variable decodes the string. Path_Info_Decoded is available to Domino applications only.
Path_Translated	/w/dc.nsf/tag/ibm	The server provides a translated version of PATH_INFO, which takes the path and does any virtual-to-physical mapping to it.
Query_String		The information that follows the ?, or in some cases the !* in the URL that referenced this script.
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.
