Paul,

Thanks. I see just these.

Connection = Keep-Alive
Date = Thu, 30 Jun 2005 00:12:38 GMT
Keep-Alive = timeout=15, max=100
null = HTTP/1.1 200 OK
Server = Apache/2.0.48 (Linux/SuSE)
Content-Type = image/png
Transfer-Encoding = chunked

Is there something that I could put in the msWMSGetMap function of mapwms.c to 
set a caching flag? I'm guessing that I could put something right after where 
the content type is set:

printf("Content-type: %s%c%c", MS_IMAGE_MIME_TYPE(map->outputformat), 10,10);

As always, any ideas are appreciated.

Doug
