[HECnet] Web-server under RSX-11M-PLUS

[Johnny Billquist]

Chunked data is basically what you use if you don't know the content length. It's in RFC2616. You basically transfer a length, followed by the data, and then a new length, new data, and so on until you've transferred it all. And then you send an end-of-data marker.
No content length needed.

RFC 2616 is the authority on all this.   Judging by a quick scan: what do you mean by "chunk data"?   If you don't specify a transfer-coding, then yes, I think 8 bit clean is assumed.   But since you mentioned "chunk" do you mean that you're specifying chunked encoding?   I didn't read all that but there's a lot of content about that in the RFC.

You'll need a content-length header, unless the connection is closed after the jpg file is transferred.   See section 4.4 of the RFC.

I also noticed a disturbing lack of funny cat pictures on the demo site...

That is related to my most immediate question. Exactly how does pictures get served in http. I tried implementing it, but I must have something wrong, so I'm trying to figure it out right now.

Questions are:
I assume the TCP stream is to be 8-bit clean. That is - no special interpretation of the byte 255 (as is done in telnet).
I assume that pictures should be ok with "Content-type: image/jpeg"
I assume chunk data should work for this I assume that all the bytes of the image should just come in the stream with nothing more involved.

Can anyone comment on those assumptions?

I have a jpeg image on mim, which I'm using as my experiment. I have checked that the contents match that of the original file which I copied, so I think the actual image is served right...

Johnny,

That's really fantastic!

Just one question, where are the dancing dogs? ;)

Ok. I just thought I'd stir some interest and just general noise by announcing that I've written a small web-server running under RSX.
It's written in BASIC+2, and uses the TCP/IP stack for RSX that I've also written. There are probably a bunch of bugs and issues still around, so I'm happy to take any bug reports, comments or whatever.

The url is http://madame.update.uu.se/, and if anyone is curious
about the code, it's at mim.update.uu.se (same machine, other IP),
under MIM::DU:[HTTPD]WWW.B2S (also on HECnet)

If people have any interest in this stuff, or something else/more, I'm interested in hearing about it. The TCP/IP stack will eventually (soon) be available for others to download and use, and apart from the web server, I've also written a telnet client, and a few small services under TCP, as well as some tools for administration. I have some polishing to do, I need to finish a DNS resolved, and I'd like to also finish FTP and a telnet server, but I might be open to distributing things before I've finished all those things, especially if someone is interested in helping writing stuff.

I have interfaces completed for BASIC+2, PDP-11 C, Macro-11. FORTRAN 77 should also work, but I haven't tried it yet.

This all runs under RSX-11M-PLUS V4.6, but I think it should be possible to get running under almost any M+ version, but there might be some hacking needed for some versions.
It will not work under 11M, and I never expect it to. One or two drivers as well as one or two tools really are big enough that I need to use the split I/D space feature in M+. Rewriting stuff to not need that is way too much work.
