[Mapserver-users] Is cgi a good solution?

[Ed McNierney]

CGI is a server technology, and Java applets and Flash viewers are client tools.  Both are separate from each other.  There are several folks using MapServer CGI with both Java applets and Flash viewers.

If you want to reproduce the effect you see you can always ask MapServer to return a map that's larger than you display (the way you hide the rest depends on the client tools you're using).  However, remember that this means EVERY map you make (a) takes longer to generate on the server and (b) takes longer to download on the client, because it's bigger.  Sometimes this is a good idea, but some times it is not.

Hi!
I recently access some other webgis solutions. some of
them use java applet and some use flash. The most
wonderful feature is that they do not only return the
image we can see in the web interface, but also the
area around it. So if the user pan a little, the user
not need to wait a little moment for the cgi on the
server to generate a new image, but use the
information already downloaded in the client to pack a
new image. So in the eye of user, it is much quicker
and smoother.
Is it a better solution?
