[GIS] What are the options for creating a tile cache via a WMS server which requires http authentication

Question

I'd like to create a tile cache and offer the tiles via TMS/WMS. The source is a WMS server that is protected by basic http authentication, but no SSL. I'll also need to reproject the tiles. This is for my own personal use. I'd prefer something that can run on either Windows or Linux, and open source is a huge plus. From some searching it appears MapServer can access WMS servers requiring authentication, but doesn't cache. GeoServer can cache WMS, but can't use authentication. Lastly, TileCache can't reproject. What are my options?

You should look also for MapProxy [1].
