Custom Map Source : multi-servers load balancing

[Laurent Grenet]

Hi all,

When a map source uses "load balancing" with several servers, this can be easily specified in custom map source file in XML format, thanks to ServerParts parameter (see : https://mobac.sourceforge.io/wiki/index.php/Custom_XML_Map_Sources#serverParts )

On the other hand, if for any reason, script is in .bsh format, is there equivalent capability ? If yes, which syntax to use ?

Thanks in advance for your answers.

BSH files are simple Java-like programs. Therefore you have a lot of options to implement load-balancing. The following example uses the tile x coordinate as indicator which server should be used:

String[] serverParts = new String[] { "a", "b", "c"};

String getTileUrl( int zoom, int x, int y ) {
   String sp = serverParts[x % serverParts.length];
   return "http://" + sp + ".myserver.example/" + zoom + "/" + x + "/" + y + ".png";    
}

OK. Many thanks !
