Custom HPSS request handlers?

[Russ Brown]

Hi,

I'm wondering if it is possible to define a custom HPPS request in a
plugin on the server, and make that request from a plugin at the client end.

The specific use case is that we have a number of repositories contain a
number of branches, and want to to be able to find out which are
candidates for removal. For the purposes of this utility, removable
branches are defined as containing no revisions that are not already
merged into the trunk branch in the same repository.

I have working code that does this already: the problem is that it is
extremely slow. So, I'm thinking that if I could write something that
would do the server-side trawling completely at the server side that
just returned the results to the client, that would speed up the
operation considerably.

So, is it possible to do this in a plugin, and if so, could someone
point me at an example of this that I can work from?

Much appreciated,
