[Mapserver-dev] mapserv (CVS) WMS query

[Yewondwossen Assefa]

Hi There,

  I am not sure if this is the appropriate way of doing this. If you 
look in the same doc (section 7.2.3.4), It specifies that :

  A client may request the default Style using a null value (as in 
"STYLES="). If several layers are requested with a mixture of named and 
default styles, the STYLES parameter includes null values between commas 
(as in "STYLES=style1,,style2,,"). If all layers are to be shown using 
the default style, either the form "STYLES=" or "STYLES=,,," is valid.



  This is what is implemented in mapserver (since Mapserver does not 
advertize any styles, the default style wich is an empty string is the 
only thing valid).

  Maybe others on the list have comments on this.

  Is is possible for your wms client to send styles=
