Idea of an apache module

[Luis Henrique Cassis Fagundes]

        Hi,
        Recently I started to have problems in developing my CGIs because in my
new job most of the servers run Netscape instead of Apache. The
administrator told me that the reason is that Netscape has a better
performance than Apache 1.3. I'm now developing a module that caches in
disk dynamic generated pages, and an interface to delete parts of this
cache when something is modified.
        Does anyone know if something like this has already been developed?
        Thanks.
