ArcWeb Instructions
===================
Before running for the first time
=================================
Copy any auxiliary applications you have into !WebHelper application. To do
this, double-click on !Webhelper and the subdirectory will be displayed.
ArcWebImg and ArcWebLcl are already installed in this directory. Before
running ArcWebTCP, you must configure the domain and the name servers
configuration file !ArcWebTCP.ResolvConf. ArcWebnTCP is ONLY for use with
Acorn TCP/IP release 2. You should also configure your mail gateway and
personal user name.
For use with KA9Q (for instance for downloading WWW pages from Demon)
the ArcWebK9Q application is included, but note that this was written by
Kevin Quinn, not Stuart Brodie.
You must copy !WebCache to a read/write filing system with plenty of space on
it. !Webhelper will run from anywhere provided that no debug options are set.
(they are not set by default).
To run it
=========
Launch !Arcweb by double-click on !ArcWeb in directory viewer, or
double-clicking on HTML files. Click icon bar icon to bring up 'home' page.
Instructions
============
Intuitive (therefore none required :-) If you get stuck, try the Problems
file.
Rather than babble on at great length on what each menu entry does, I
recommend loading the Acorn !Help application and then an exploring of the
menus. !ArcWeb, !ArcwebLcl and !ArcwebImg support full interactive help on
all windows, dialogue boxes and menus.
Basically: To follow a link, click SELECT over it; to open a new page choose
Open URL from the Navigate menu over a document (or from the icon bar menu).
If you want to interrupt the drawing of the page, then double-click on the web
icon at the top of the drawing and drawing will cease allowing you control.
Configuration
=============
If you are going to be using ArcWebTCP, You MUST reconfigure the resolver
configuration file !ArcWebTCP.ResolvConf. The first line of the file
should be your Internet domain (with trailing .) and then up to three
'nameserver <ip address>' lines specifying name servers which can be used to
look up hostnames. Do NOT leave the file as is (pointing to my own domain
ecs.soton.ac.uk. and nameservers 152.78.64.201 152.78.128.78 152.78.128.79.
You MUST use IP numbers and not host names. NOTE: my *hostname* is
delenn.ecs.soton.ac.uk so my *domain* is ecs.soton.ac.uk.
The 'home page' is controlled by an environment variable Arcweb$Home. If
this variable is not set when ArcWeb is run, it will set it to a default
document within an ArcWeb subdirectory.
The 'cache directory' is controlled by an environment variable
Arcweb$CacheDir. If this variable is not set when ArcWeb is run, it will
set it to a default directory within an ArcWeb subdirectory. The !WebCache
application supplied contains a !Boot file which initialises this variable
to a subdirectory of itself.
To flush the cache, open the !WebCache directory (hold down SHIFT and
double-click the !WebCache icon in a directory viewer), and then double
click on !Wipe. This will remove the cache directory entirely.
Don't put extra files in the cache directories. The cache manager will find
these and remove them. By default it allows 77 files to be cached (no size
limit) (where have I heard of a limit of 77 before :-/) so it doesn't want
other things clogging up the directory. The cache manager will remove
anything not in the index, and remove anything from the index which doesn't
exist in the sources directory. IF the Cache Manager cannot remove a file
(because it is open for example), it will leave it there.
Every 60 seconds, the cache is checked for documents which have passed their
expiry date. These old documents are removed (unless they are currently
being fetched, or are currently being viewed, or if it is inlined image
which is part of a currently being fetched/viewed document.)
Full Icon Bar Problem
=====================
From version 0.13 this is not a problem as ArcWebLcl and ArcWebImg are
supplied configured not to install icon bar icons. ArcWebTCP is
configured to install an icon so that you can change the proxying
information. See the Problems file for details of how to reconfigure these
three programs.

Thanks for your help,
