------------------------------------------
(moving the discussion to the dev list)
> URI path split is content dependent
> -----------------------------------
>
> Key: SLING-60
> URL: https://issues.apache.org/jira/browse/SLING-60
> Project: Sling
> Issue Type: Improvement
> Components: microsling
> Reporter: Felix Meschberger
> Fix For: 2.0.0
>
>
> I have a conceptual issue with the SlingRequestPathInfoParser because the
> idea of cutting an URI path into pieces is different and the
> SlingRequestPathInfoParser just does not have enough knowledge to break the
> URI path apart.
> The initial intent of breaking the URI apart such, that the resource path is
> the the longest prefix of the URI path matching a repository item (I think we
> should move to enabling addressing items and not just nodes...) and the rest
> of the breakup depends on the first part.
> So a simple implementation would be to cut off pieces of the URI path from
> the end at dots and slashes until a repository item may be addressed. What
> has been cut off is then further treated like this:
> * Any pieces separated by a dot from the path in the same path segement
> are considered the
> selectors and extension.
> * All pieces together after the last segement of the item path make up the
> suffix.
> Examples:
> /a/b/c.print.a4.html/some/suffix.pdf with an item at /a/b/c would be broken
> apart as resourcePath=/a/b/c, selectors=[print,a4], ext=html,
> suffix=/some/suffix.pdf
>
> /a/b.special/c.print.a4.html/some/suffix.pdf with an item at /a/b.special/c
> would be broken apart as resourcePath=/a/b.special/c, selectors=[print,a4],
> ext=html, suffix=/some/suffix.pdf
>
> Simple string operations cannot account for this subtelity. For this reason I
> propse to drop the SlingRequestPathInfoParser class and implement the split
> up in the ResourceResolverFilter or an abstract base class thereoff.
> See also the ContentResolverFilter in the Sling Core project.
