Hi all I'm sitting in Phom Penh and have very slow internet. The tiles come in very very slow.
I'm working on a new javascript map... full story: http://www.mail-archive.com/[email protected]/msg10669.html The internet is too slow here for developing, so I had to install a local image proxy. Now it's fast as hell. It's faster than at home. If a tile is changed I will see the old version for a long time. But it's fast and usable. ----HTTP HEAD Google Cache Time: Cache-Control: public, max-age=22222222 //feels like one month (I didn't calculate) OSM Cache Time: eTag (no cache) ----- Story In many countrys (like cambodia) the ping is very long. It can be easily some seconds. osm.org is slow slow slow. It takes long time until all the tile for the osm startpage are loaded. But then the problem starts. Every move I make on the map is soooo slow. Even if I was looking at the same spot on the map a couple of days ago. For visitors of osm.org a good caching is important. For editors of osm.org it's important to have the newest version of the tiles. For visitors (not logged in) there could be a diffent caching than for editors (logged in). Caching is important if you sit somewhere in a developig country with slow internet connection. ----Implementation Tileserver visiter cache.openstreetmap.org Tileserver editor tiles.openstreetmap.org The Servers should deliver headers for long and short caching time. The map for logged in users should load images from tiles.openstreetmap.org. (extensible rules...) Never mind, I was just thinking about that and want to distribute it. Wish you a nice day Bernhard ------OSM: HEAD http://a.andy.sandbox.cloudmade.com/tiles/cycle/17/37480/50153.png 200 OK Cache-Control: max-age=440434 Connection: close Date: Fri, 05 Mar 2010 14:37:11 GMT ETag: "d096ddafba32c0da609007e224530ccd" Server: Apache/2.2.8 (Ubuntu) Content-Length: 45409 Content-Type: image/png Expires: Wed, 10 Mar 2010 16:57:46 GMT Client-Date: Fri, 05 Mar 2010 14:37:11 GMT Client-Peer: 75.101.147.222:80 Client-Response-Num: 1 -----GOOGLE: HEAD "http://mt1.google.com/vt/lyr...@118&hl=de&x=3&y=6&z=4&s=Galileo"; 200 OK Cache-Control: public, max-age=22222222 Connection: close Date: Fri, 05 Mar 2010 14:45:02 GMT Server: maptiles-versatile Content-Length: 19810 Content-Type: image/png Client-Date: Fri, 05 Mar 2010 14:45:02 GMT Client-Peer: 64.233.189.136:80 Client-Response-Num: 1 X-Content-Type-Options: nosniff X-XSS-Protection: 0 Sorry, I posted something similar bevor: http://www.mail-archive.com/[email protected]/msg23461.html Bernhard _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
