The naming of the project is probably incorrect (since I didn't really worry
about it compared to the code), a more complete one is (here
http://fsdev.net/repositories/browse/dsss/trunk/backend ) but I haven't merged
some of my changes and besides that, I think those changes were lost in my last
windows crash (since I was on windows then if I'm correct). However, it's a
pretty good starting point. Some of it may need to be updated to latest tango
though. At the moment it's a framework pretty much where the application has 3
layers.. the framework, which is protocol independant, the protocol dependant
stuff (ftp/http/SOMEODDCREATION) that is a basic set of hooks that comply to a
certain function definition and when initing the backend, hook itself into it
to get the stuff over the protocol, and then their is the command line level
which controls managing all this....
http://fsdev.net/repositories/browse/dsss/trunk/backend It's got the backend
pretty much finished if I remembe!
r correctly and I had started works on the midend hooks for http and ftp, and
then lost that work. It shouldn't be super hard if I remember correctly and it
should also all compile (if I remember correctly).
