Re: [mapserver-users] conf of MapServ+Apache.Lighttpd for better usability
This would be a good thing. That way, if you would zoom in to a location very quickly, you would also not have to wait for mapserver to render the outer zooms first (where you clicked through quite fast), but you would get your data first and the data you don't need anymore later. But i suppose this is not easy to realize. On 2 November 2010 18:40, Sebastian E.

Hi, Just a thought here, but have you considered using a threaded server? e.g. aolserver? Are you able to run in-process? Also, IIRC, thgere's a switch in the mapfile to keep the postgres, maybe the oracle connection open to save the connection overhead...
