I've checked in some changes to the fetch / cache / content stuff. The memory cache now holds documents as they are loading. Each content also has a list of users. The only visible change should be that loading the same page in two windows simultaneously will now work properly (before, only one would notice that the page was complete). The memory cache still needs some work though, so NetSurf may run out of memory often. The new 'other' content is for downloading files. Does anyone want to implement the front end for this? Let me know and I'll explain what needs doing. Also, I've put together a way of compiling the back end to a command line program under linux, which makes debugging back end problems easier. I'll check that in soon. James
