Webservers are usually used in a public facing way and which is how
I used them on VMS.

However, the last time I ran a webserver on VMS was 15 years ago and
even then I was skittish about doing that.

I also thought that Phillip was presenting various services on his

with various questions he has asked here.

Does it write the file data to a temporary file ? DCL symbols are
not capable of holding the contents of a file unless it's extremely
small.
