But the client could also be a Java applet (Jbox, Rosa...) or flash ecc.
Then for me the client is the whole browser, howevrer this is not important.
In order to select multiple features, you will need to use 'classic'

Don't know about this, however with Mapserver in cgi mode, u could build a
query like this:
"&imgbox="+imgbox +"&savequery=true&map_querymap_size=140 120";
pure Java, Flash ecc.) .
For opening query results in a new page, it's possibile but as said, it
depends on tecnologies used (I think).
URL the parameters u use to do the query (mode, imgext ecc..).
One client that does support

Yes, and also the above jBox (the dbox equivalent in Java) and Rosa applet
(I don't know if there are
other Open Source clients...).
