Hm,

I think you have a valid use case, but our end user's use case is as
valid as the one that you describe. So the filter approach solves one
problem by bringing in a problem that didn't exist before. To me it
seems not a good strategy to make the usage of Equinox on the serverside
more popular by suggesting to our users to patch bundles to solve such
problems.

I would prefer an approach e.g. that allows to declare such filters
independently from the servlet/resources registration. This would solve
the problem you describe and still allows people to use the help.webapp
bundle.


Ciao

Hi Frank,

I'm afraid you need to patch the help plug-in to register with *any*
HttpService available (or use an alternate filter if necessary).

I can't comment on why it was introduced the first time. However, I have

a use case. I'm developing a platform which provides multiple
HttpService instances. One is for "public" stuff and the other for
"admin" stuff. Think of it as an admin/system back office which - in
addition to being password protected - must also be hidden from the
public port.

Yet another use case might be virtual hosting or SSL sites. Some content

should only be available over an SSL connection.

FWIW, I actually patched RAP to only register with a specific service
instance. This works well for the actual servlet but not for the
resources.
