- That's a very good question, as lots of companies have this
- restriction.
- Fortunately, the browser is set up so that you can
- pass requests (according to protocol in the document id) to a
- gateway. You can on the client node setenv WWW_http_GATEWAY and
- WWW_wais_GATEWAY etc to point gateway addresses. At that address you
- need to set up a server to access the remote whateveritis and send
- the results back as hypertext.
-
- HTTP gateway:
-
- I've just tried this and it seems to work fine. You use the www
- client as a server. On your gateway machine,
-
- 1. Put a new service (htgate, 8002 say) into /etc/services or
- whatever you use instead.
-
- 2. Set up inetd.conf to run /usr/local/bin/htgate when a tcp
- connection to htgate comes in. You have to kill -HUP the inetd
- process to get it to take the change into account.
-
- 3. Use this htgate script which reads the command line and then calls
- www with its second parameter and sends the source to the caller:
-
- #! /bin/sh
- read get docid
- /usr/local/bin/www -source -n -na -p "$docid"
-
- That will handle anything where the source is HTML. It won't handle
- internet news, gopher, etc. (For that we need an option on the
- browser -html which generates HTML
- from news, etc, which we haven't done yet -- but you're not the first
- to ask)
-
- I suggest you run the wais gateway separately, but you could change
- the shell script to check the protocol on the doc-id and run www or
- WAISGate as appropriate. That means you set separately on the client
-
- setenv WWW_http_GATEWAY http://gate.hal.com:8002/
- setenv WWW_wais_GATEWAY http://gate.hal.com:8001/
-
- For the wais gateway, you get the sources from info.cern.ch
- /pub/www/stcWWWDaemon_v.vv.tar.Z and compile it. The documentation is
- http://info.cern.ch/hypertext/WWW/Daemon/User/Guide.html and linked
- documents.
-
- I hope this solves the problem and opens up the web for the
- organsiation. If you need the option for news or gopher, we'll have
- to put the -html option in. Let me (and the list) know how you get
- on...
