The latest Apache::ASP release code makes the $Response->AddHeader() code go through the ExpiresAbsolute API for the Expires header. This is good in that people setting ExpiresAbsolute as a member & as a header won't create duplicate headers as was the point of the fix. > This worked in Apache::ASP 2.07. > > How do I manually set the Expires header with new versions?

The Expires header is supposed to be an HTTP date header of a very particular format, not 0 which is likely an illegal value ( not sure but probably ). This format is: Wed, 09 Feb 1994 22:23:32 GMT which is what one would expect being passed to $Response->AddHeader('Expires', $value); or with direct API $Response->{ExpiresAbsolute} = $value; What you probably should use for what you want is $Response->{Expires} = 0; which will convert 0 to the HTTP date formatted for the currect system time. Note that because this expiration is web client driven, and because client system clocks may be set incorrectly, you should probably set 0 to be a large negative number like: $Response->{Expires} = 86400 * -400; # expires 400 days ago This will let the page to expire immediately for even clock set to a year behind!! ( probably a more frequent occurance that one might think ) --Josh _________________________________________________________________ Joshua Chamas Chamas Enterprises Inc.
