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.

Subject: [OpenLayers-Users] Problem with maximum URL length
Hi all,
I have a project with many WMS layers which have rather long layer
names. Now I seem to be hitting a maximum URL length restriction of
IE
in the GetFeatureInfo request. See also
http://support.microsoft.com/kb/208427
Do you have any ideas for a workaround? Would a post request work
with OpenLayers.Control.WMSGetFeatureInfo ?
My project has >50 layers with rather long names and while debugging
I saw that the URL was around 3000 characters long. IE just cut the
URL off at 2047 characters and my WMS server resulted in a 500 error
code.
Any ideas?
Thank you very much,
Andreas
