[mapserver-users] querymap mode

[Grzegorz Myrda]

Yap, I know. It was clarified a few times on the list.

But In my opinion querymaps are not exactly normal maps.
The way they are generated has some consequences.
Differences are:
-itemquerymap returns just image, not template, so mapserv is called 2 times (first to return template, second to return querymap which is not saved to temporary file)
-map is generated from mapserv parameters used in [img] tag. So to modify map looks like, you have to modify template source. In case of normal maps you modify only URL.
