The maxGetUrlLength
property of the layer's
tileOptions
option causes tiles to be requested using
HTTP POST when the length of the GET url would exceed the specified
length (2048 characters is recommended). In real life applications,
this happens often when using the SLD_BODY request parameter for
inline styling.
Long URL - POST requests
Short URL - GET requests
