@prologic@twtxt.net: Reduced refresh interval to 7200 seconds :-)

@prologic@twtxt.net I guess that refresh field could be easily replaced with Expires HTTP header (I realize that users on neocities.org cannot control this header, for example). And clients should also respect headers like Last-Modified/If-Modified-Since (304), you’re right about that. P.S. twtwt doens’t have a caching mechanism for now, but I plan to implement it in generic way using HTTP headers.
