Hi I gave it another try and let it run for awhile and it appears to eventually work.<br>I mean, I have set the redraw_interval to be 30 seconds and the refresh_interval to be 60 seconds. It takes usually three refreshes before the changes appear on the map.<br><br>S.D.<br><br><b><i>"Delfos, Jacob" <Jacob.Delfos@maunsell.com></i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> <meta http-equiv="Content-Type" content="text/html; charset=us-ascii"> <meta content="MSHTML 6.00.2900.2912" name="GENERATOR"> <div dir="ltr" align="left"><span class="209211923-30072006"><font color="#0000ff" face="Arial" size="2">Samuel,</font></span></div> <div dir="ltr" align="left"><span class="209211923-30072006"><font color="#0000ff" face="Arial" size="2"></font></span> </div> <div dir="ltr" align="left"><span class="209211923-30072006"><font color="#0000ff" face="Arial" size="2">I didn't mean for you to

included the redraw_interval and have tried the various combinations even setting tile_source to nocache setting the redraw_interval to be both greater then and less then the refresh_inteval even though it looks as if it should be less then what you set for the refresh_interval. In the end In the end I always end up needing to delete the tiles directory populated by mapserver in order to get them regenerated again.<br><br><b><i>"Delfos, Jacob" <Jacob.Delfos@maunsell.com></i></b> wrote: <blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); padding-left: 5px; margin-left: 5px;"> <meta content="MSHTML 6.00.2900.2912" name="GENERATOR"> <div dir="ltr" align="left"><span class="081521701-28072006"><font color="#0000ff" face="Arial" size="2">Samuel,</font></span></div> <div dir="ltr" align="left"><span class="081521701-28072006"><font color="#0000ff" face="Arial"

poking around and guessing at based on what I noticed in the KaMap code I have place a refresh_interval value in a metadata section within a layer in my map file. Now, I can see a periodic update on the map but the problem is when I have modifed a dbf file under mapserver those changes are not reflected. So the question is, is there something I need to do special to get MapServer or KaMap or whatever to detect an update done to a map so that it is served properly?? These changes to the map files are being done programatically and not by hand.<br><br>Thanks, S.D.<br></blockquote></blockquote><br></blockquote></blockquote><br></blockquote></blockquote><br>
