I have some doubt that such a thing would be a good idea. First, there's the issue of whether archiva ought to be modifying the content it serves, and how this will break checksums. However, more importantly, this would mean that knowledge about proxy specific URLs was being embedded into POMs in the local repository. This would be a severe problem for laptop users who use a variety of different profiles to vary mirror settings dependent on location. It would also make things unnecessarily difficult for people in any situation to cleanly and simply change their proxy configuration in any way. Perhaps instead, this could be handled by linked improvements in maven and archiva, allowing maven to autodiscover the list of repositories an archiva instance is proxying, given only the base url of the archiva instance. Or, alternatively, a maven could operate some simple encoding scheme, contacting archiva passing on the full upstream URL that it is interested, and archiva could either serve it, or decline. Either option would avoid the mirror configuration becoming entangled in the local repository, which I think is a very important thing. Max.
Re: Proxy vs. Repository URLs
URL Name was introduced to make the repository snippets make sense.
consider the following
repository
idsnapshots/id
urlhttp://archiva.corporate.com/repository/snapshots/url
/repository
vs
repository
idcorporate.snapshots/id
urlhttp://archiva.corporate.com/repository/snapshots/url
/repository
One future feature for archiva is to manage the pom internal
repositories to point to itself.
In other words, if archiva is told to proxy central, and a pom gets
pulled down pointing to a new repository of say ...
repository
idsf.net/id
urlhttp://projfoo.sourceforge.net/maven2//url
/repository
then archiva should replace that entry with itself so that the requests
at the maven client continue to hit the corporate repository.
We need to have a more sane / verbose id field, as that is what is used
in maven client for log messages and the like.
But having a more verbose id field for the url make no sense. hence the
split.
For the record, I don't like the /proxy/ servlet in archiva.
It has no security!!
It will be removed.
And the /repository/${urlname}/ will have the proxy abilities (with
security)

To use it as a normal repository, the url is

To use that same repo as a proxy, (as far as I can tell, with maxb's

Is this correct? If so, why do we use the 'URL Name' in one place and
the 'Identifier' in another?
+1 to using the identifier in both.

We need to have a more sane / verbose id field, as that is what is used in maven client for log messages and the like. But having a more verbose id field for the url make no sense. hence the split. This is a great example of why id or name is of no value. Consider another project: repository idsf.net/id urlhttp://another_project.sourceforge.net/maven2//url /repository Since there can be no enforcement of the content of id/name it is too easy to get shadowed. It is impossible to shadow the url. The other problem is displaying information messages that include the id. Since a repository can be defined in ANY pom in the transitive dependency list there is no easy way for the user to find out what the definition of sf.net actually points to. This only affects people with firewalls, as it does me, because I need to put in a security request to get the url of sf.net opened up as an unauthenticated proxy. At least until either maven or archive can support NTLM authentication (or I convince people here to ditch NTLM and use LDAP). Yes the information messages will be longer by pointing to URLs but it may be better from a useability point of view.

I'd prefer to drop the identifier completely. The URL is unique and should be used as the identifier. At least that way it stops having so many synonyms in pom files, which is damn annoying.
