hello. Having seen webdav read/write/browser support there for years. The original plugin for webdav was written about a decade ago and taken down many years ago.

I am a user and I cannot program (yes I know jEdit's tagline is "programmer's editor but I somehow ended up using jedit for editing my non-program-source-code files) but if a programmer have time and come by you can consider adding this feature:)

If you consider putting support of webdav into jedit, perhaps you can also consider being compatible with gnome's URI convention. Right click in gnome and choose open a webdav file in gnome results this command being called:

jedit dav://username@server.domain.name

I don't see it important to support gnome-vfs but supporting the same URI convention would help a lot already.
