[users@httpd] How to resist user click abuse in apache?
Here is the situation. Heavy db driven site takes about 1-1.5 second
to load some pages. While loading such page it takes a lot of memory
and cpu. It is not a problem it is used normally, but some users are
very hasty and stupid. When they do not get page within 0.1 seconds
they click the link to the page again, sometimes 5 times a second.
What would be a good way to resist such abuse?
For example, allow certain amount of simultaneous connections to
some locations and another number of simultaneous connections for
another location (for example, more connections to the dir where
images are stored).

I wouldn't call those users "hasty and stupid"... I'd call them "normal".
The à la mode solution to this type of thing is to use javascript to play a "loading..." animation and disable the user input - look up dojo, scriptaculous, prototype etc. for toolkits that do this sort of thing.
