HTTP::Cache vs HTTP::Download and HTTP::Header

Hello pear-dev, HTTP::Cache vs HTTP::Download and HTTP::Header If there is such thing as usability in PEAR, then I must admit, that above conflict directly relates to it. As an unexperienced developer I know which packages PEAR contain but I just don't have time to read each and all descriptions available on the site. I can only presume, that HTTP::Download implements something like PEAR wget and HTTP::Header is for some mysterious HTTP headers manipulations or for statistics or whatever. It was a big surprise to know them capable something else. From my POV if I need to implement Cache Control for my site, I will feed google these words "cache control php package". Useful package is not that it contains many features, but one, which developers know about and use. I'd like to have some HTTP::Cache_Control, which specializes only on this part of HTTP protocol, even if it will bear some of the other packages functionality. But this one should implement the ultimate Caching mechanizm if it is possible. =) t --
