At least it should work :-) So if you like you can try it.
OTOH after months of being occupied with other more pressing matters
I started my WebDAV server on webdav.ethz.ch again.
And I will have look into the problems there are.
The difficult part is that I fear that these are not WebDAV but TCP/IP/HTTP

Bad news :-(
But I don't think it's possible for the (very small) Oberon community
to provide a better browser. Even if it's perhaps not giving
many academic laurels I think that an OS which hasn't at
least some decent capabilities for browsing the Web doesn't have
a great appeal to new people. So I can only beg ETH to invest some
energy e.g. to integrate the good stuff from WebNavigator (Some support for
frames and CSS) into the standard browser.
A decent browser is basic stuff nowadays which is expected of an OS of any
value. Or what about a WINE for Oberon ? I just installed it on my Debian
today to see what it's capable of.

I saw that you tried to upload XMLRPC.Mod to webdav.ethz.ch and that you
didn't succeed. The file only has 512 bytes and half of them are junk.
I assume that there are still problems somewhere in TCP/IP which are probably
also the cause of the FTP problems discussed recently.
AFAIK there was a major rewrite of the Aos TCP/IP and this wasn't simple.
Even when upload from Aos worked also for files of more than e.g. 50K I had
problems with uploading files of this size from NO.
So is there any hope that NOs TCP/IP will be fixed to work with Aos (Assuming
for now that it has a problem) ?
Having finished some other things I problably will have a closer look at
WebDAV again the next weeks.

Cheers, Edgar
