- Hints & Tips
- ============
-
- This file contains hints and tips for running ArcWeb. Some of these are
- mine, others are ones I've seen posted on the net or had emailed to me.
-
- There are so many contributors that it would take too long to list them
- all.

- Using RAM disc for the cache
- ----------------------------
-
- Several people have noticed that if the cache is set to a directory in a
- suitably large RAM disc, speedups occur. I have tried this myself, but
- I couldn't detect much difference, although I did only try it with
- smallish documents and images. Obviously you lose the entire cache
- when you reboot. I would imagine that you need quite a generous size,
- at least 8MB to be safe.
-
-
- Aborting a fetch
- ----------------
-
- You can click on the animated web icon to request that a fetch is stopped.
- This works all the time, whereas the Stop button only interrupts during
- the page rendering.
-
-
- Clickable images
- ----------------
-
- Some images are sensitive to mouse clicks so that if you click on a
- particular part of the image, you visit a different page. These
- 'imagemaps', as they are called, are very pretty and nice to use -
- you can see an example at http://www.acorn.co.uk/ where the signpost
- is one of these 'imagemaps'.
-
- The problem with imagemaps is that when you click on a particular part
- of the image, the browser has to carry out TWO document retrievals in
- order to process that click - the first is a request to the server to
- ask it which document it should view, and the second will be the real
- request. This will cause a longer delay in retrieving the document than
- would be the case normally.
-
- While the WWW developer community is working to address this problem,
- there is a workaround for users. Using Acorn's home page as example,
- you will see a mini-menu underneath the image representing all the
- destinations which are contained in the image. Clicking on these links
- will omit the first step mentioned in the previous paragraph, and go
- directly to the page concerned.
