- Introduction
- ============
-
- I realise that it may seem that you have to read a lot of instructions
- before you can do anything, but I've tried to spell it all out in as
- much detail as possible in an attempt to pre-empt the common problems
- which people have had in the past. I get so many e-mails about the
- "Too Long" problem, still.
-
- This file gives some instruction on how to get ArcWeb up and running at least
- on a local basis. Once this has been achieved, there are help files supplied
- in HTML format. Run !ArcWeb and click SELECT over the icon bar icon to open
- the index page, and then you can follow links to information about the helper
- applications and their configuration. I suggest you read the instructions
- for network configuration very carefully. There are instructions further
- down for upgrading your current ArcWeb to this version.
-
- If you get stuck, try the Problems file. This is a FAQ style document
- containing around 20 common questions and answers.
-
-
-
- Before running for the first time
- =================================
-
- ArcWeb cannot do everything itself. It needs 'helper' applications. These
- are stored inside the !WebHelper application. KA9Q users need to read the
- section immediately below. FreeNet/Acorn users can skip to the next
- non-indented paragraph.
-
- KA9Q users only
- ---------------
-
- This version of ArcWeb is unlikely to work with KA9Q. I suggest
- that you investigate FreeNet or Acorn TCP/IP release 4.
-
-
- Copy any auxiliary applications you have into !WebHelper application. To do
- this, double-click on !WebHelper and the subdirectory will be displayed.
- !FilerURLs is already installed in this directory. You must configure your
- e-mail address and on-line news server name (if you have one). See
- 'Configuration' below.
-
- You may choose to install things like SoundCon inside !WebHelper so that
- they automatically load when ArcWeb does.
-
-
- Patching ChangeFSI
- ==================
-
- Read the instructions in the file "ReadMeDocs.JPEG_Fix" for instructions
- on modifications that should be made to ChangeFSI in order to enable it
- to support more types of JPEG image.
-
-
- How to install the DNS configuration files
- ==========================================
-
- If you are not already running a FreeNet configuration or using
- InetDB or DNSResolver, you will need to install the DNS configuration
- files in your InetDBase$Path directory. You do not actually need
- the DNS module running, as ArcWeb contains a DNS resolver anyway.
- If you are using ANT !InetSuite, then you need to install part of
- the DNS resolver - the configuration file - inside !InetSuite.
-
- The Name Lookup service is responsible for asking other machines
- (nameservers) to convert hostnames which the user sees (like
- delenn.ecs.soton.ac.uk) into IP addresses (like 152.78.67.42) which it needs
- in order to be able to connect to a given machine.
-
- You need to ensure that the configuration files are already present in
- the files database (InetDbase$Path - typically !Internet.files or
- !FreeUser.files)
-
- Read InetDB.ReadMe1st for more information on configuring the files.
-
-
- 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.
- All applications inside !WebHelper will be loaded automatically.
-
- 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 supports 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).
- Alternatively, to go to a specific URL you can enter it in the icon at the
- top of an open ArcWeb page.
-
-
- If you get 'Too Long' errors
- ============================
-
- Quit !ArcWeb. Move !WebCache closer to the root directory of the device on
- which they are stored, and then 'run' it by double-clicking on its icon.
- See Problems Q18 for more details of why you must do this.
-
-
-
- Configuration
- =============
-
- You MUST reconfigure the e-mail address and the news server address. Click
- MENU over ArcWeb's icon bar icon and choose "EMail & News" from the
- "Configuration" menu to open the configuration window. You may wish to set
- up proxy servers for HTTP, FTP, gopher and WAIS in the Network window.
- ArcWeb will handle FTP and HTTP and gopher itself if you want it to.
-
- More help is available by clicking SELECT over the Information icon (the same
- as !Help's icon) at the top of the Network window.
-
-
- How to change the default page
- ==============================
-
- The 'home page' is controlled by an environment variable ArcWeb$Home. If
- this variable is not set when ArcWeb is run, it will set it to a default
- document within an ArcWeb subdirectory.
-
-
- How to change the cache location
- ================================
-
- The 'cache directory' is controlled by environment variable Arcweb$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. This allows !ArcWeb to be stored in a read only filing system.
-
- Don't put extra files in the cache directories. The cache manager will find
- these and remove them. By default it allows 75 files to be cached (no size
- limit) 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.
-
- How to remove everything from the cache
- =======================================
-
- Open the Cache configuration window and click on the 'Flush images' or 'Flush
- everything' menu items. You will be prompted to confirm the action.
-
- Every so often, 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.). This facility
- can be disabled in the Cache configuration window. The frequency of the
- checking can also been configured from there.
-
-
- How to control the authentication database
- ==========================================
-
- The 'authentication database' holds a cache of servers and their realms which
- have required authentication in the current session. By default, it is wiped
- when ArcWeb exits (but can be reconfigured in the Network configuration
- window) as a security precaution. Its location is controlled by
- ArcWeb$AuthFile which is set by !WebCache or !ArcWeb when it is run and
- !WebCache hasn't set it yet.
-
-
- Running with RISC OS 3.60 and later (inlining JPEGs)
- ====================================================
-
- ArcWeb 0.37 and later contain support for inlined JPEGs - a facility
- built into the RISC OS ROMs in RISC OS 3.60 and later. Since I do
- not have a Risc PC700 to test with, this feature is not enabled by
- default as I have no way of testing it personally. To the best of
- my knowledge it will work though.
-
- To enable the JPEG option, enable the option in the Browser configuration
- window. If the option has been used, ArcWeb will verify that you have
- SpriteExtend 0.80 or later before attempting anything clever. (In fact
- it makes it unselectable if you don't have a suitable module).
-
- It appears that Draw has a problem with the draw files that I export with
- contain JPEGs though. I'm not sure why this is at the moment and it is still
- under investigation.
-
-
-
- Configuration of ArcWeb
- =======================
-
- All the configuration windows are available on the Configure submenu
- of the icon bar menu, and from the Options menu on the page menu.
- See the Problems file for more on how to reconfigure these programs.
