[mapserver-users] Left click loses CGI variables

[Stephen Davies]

I have MapServer 6.4.1 running on a CentOS 7 server with clients scattered all 
over the country with a variety of devices from full-blown PCs to iPhones and 
various Android devices all using a variety of browsers to view maps.

Users with PDA devices (anything too small to be able to handle legends etc) 
are served with a direct call to mapserv (Generated from a menu selection 
after login).

eg: 
http://www.agua.com.au/cgi-bin/mapserv?map=/tmp/11_63.map&client=63&dpi=96&LOC=&mapext=138.5417058+-35.2605136+138.5435908+-35.2562368&mre=-1074567.04+-4230140.65+284643.94+-2872042.86&pfilter=logger_id+in+%28select+id+from+logger+where+63=any%28client_id%29%29&bfilter=id+in+%280%29&wfilter=id+in+%280%29&ufilter=probe_id+in+%28451%29&MB=M&PID=&ET=D&sdt=18/12/2014&envfilter=

The *filter variables are all used for run-time substitution.

The above produces the correct result as each filter variable has a value.

However, if the user then clicks the map, the *filter variables are lost.

I don't necessarily see this as a MapServer problem; rather as something I am 
doing - or not doing.

Cheers and thanks,
Stephen
