UrlResource should support lastModified() for http URLs [SPR-5465]

[spring-projects-issues]

Justin Edelson opened SPR-5465 and commented

The lastModified() method of org.springframework.core.io.UrlResource only works for URLs that can be resolved to files. For HTTP URLs, a HEAD request could be made to get the Last Modified header.

Seconded. I was really quite surprised to find that this wasn't the case already, although I appreciate that there might be complexities in this one.

Finally added for Spring 3.0.4, as part of a general refinement of the Resource abstraction - we added a "contentLength()" method as well, for example.
