[OpenLayers-Users] Problem with maximum URL length

[Andreas Neumann]

 Hi again,

 Parts of the problem is that the long list of layers is repeated: once 
 in the LAYERS parameter and once in the QUERY_LAYERS parameter. That way 
 one can easily hit the limitation if one has a list of layers with long 
 names.

 So the solution seems to be to use a POST instead of a GET request. But 
 I think we will have to patch OpenLayers to use POST instead of GET. I 
 see that the OpenLayers.Request object would support POST requests, so 
 we'd have to patch the OpenLayers.Control.WMSGetFeatureInfo to expose an 
 additionals request method parameter (GET|POST) and forward it to the 
 OpenLayers.Request object.

 I already asked the programmer of my WMS server if he can support the 
 POST requests and it seems they can with a little extra work.

 I am bit suprised that I seem to be one of the few people hitting this 
 limitation.

 I will write a feature request in the OpenLayers trac and provide a 
 patch.

 Andreas
