[ka-Map-users] Can someone answer this question please or tell mewho I should ask it to?

[Samuel Doyle]

Hi,
 Yes, for my test I manually change the dbf files and verify that the timestamp is different. I would assume it is the same URL since it is the same file? The tiles are re-written only when I manually remove them. I haven't tried the option you suggest in tile.php. I will try that tomorrow. I haven't noticed a timestamp directory. Is there supposed to be one? Yes, it would appear that the same tile or  none is being generated since the change can be seen when I clear the tiles directory and then they are regenerated. What should I be looking for? I mean is there some naming conventions or pattern I should be looking for? I have just started working with both kamap and mapserver and without any documentation it's a bit of a go.
 
 Thanks for your response,
 
 S.D.

 Have you checked whether the URL is actually different?  Are you saying it serves out the same tiles, despite the different timestamp?  Did you check whether any tiles actually get re-written?
 Have you tried playing with the "force" parameter of  tile.php? If this creates a new tile, it means the problem is it decides it  doesn't need to be re-created. If "force" doesn't work, it means it isn't able  to re-create the tiles. 
 Is there a timestamp directory  present?

Thanks for the repsonse.

Yes I have 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.

     Have you looked at the redraw_interval, described in      init.php? That appends a timestamp to the URL of the tile, to      force redrawing of the tiles. refresh-interval only does a      re-request, returning a cached tile.

Sorry but I haven't received any answers for the questions I        have posted here but this one is a bit important.

After 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.

Thanks,    S.D.
