MapXtreme Tile Handler

MapXtreme v7.1 97 Developer Guide

Caching

The MapXtreme Tile Handler supports caching of frequently used tiles so that application

performance does not suffer. Caching instructions are included in the web.config file following

Microsoft’s.NET Framework HttpCacheability.

Five types of caching (plus a no cache option) are supported. These enumerated values are used to

set the Cache-Control HTTP header.

TileServer The path to your instance of the MapTiling handler.

This must match the beginning of the "path" entries

in the "httpHandlers" section of your web.config.

See above.

mapname The name of the map on the Tile Server.

level The level of requested tiles. Zero-based.

x;y The x and y ordinates of the requested tile (zero-

based).

For example, at level 3 the map consists of 64 tiles

in 8 rows and 8 columns. The x and y arguments for

the upper left tile would be 0;0. For the lower left

tile, it would be 0;7.

ext An extension denoting the format of the tile (e.g.,

.gif, png). Must match a supported format.

Argument Description

NoCache Sets the Cache-Control: no-cache header. Without a field name, the

directive applies to the entire request and a shared (proxy server)

cache must force a successful revalidation with the origin Web

server before satisfying the request. With a field name, the directive

applies only to the named field; the rest of the response may be

supplied from a shared cache.

Private Default value. Sets Cache-Control: private to specify that the

response is cacheable only on the client and not by shared (proxy

server) caches.

Public Sets Cache-Control: public to specify that the response is cacheable

by clients and shared (proxy) caches.
