1. I just got a problem with your new httpd on

When I tried to access the file:

with xmosaic 0.10, I got the following error message:

HTFormat: Sorry, can't convert from application/binary to www/present.

The line-mode browser www 1.3a produced the same error message.

With www 2.0 an empty page were produced.

After that I tried to use the new binary transfer mode feature of mosaic.
The result was a file with the above error message.

The same problem occured with other files referenced from:
for example: text2html.sed

2. Is it possible to get the files referenced from:
via ftp ?

Or can someone put the files on under /WWW/dev ?
