PART 17: Customizing WWW
------------------------

This is the seventeenth part of a series of postings describing the concept 
of the World-Wide Web and guiding anyone who is interested in obtaining and 
setting up the software required to access the Web.

WWW browsers come with an address of a document to start with, a so-called 
Home Page. Usually, this document does not include pointers to the WWW 
sites you are interested in. Accessing information by following the 
hyperlinks provided may therefore take some time. A quicker and more 
convenient route to the World-Wide Web is to use your own Home Page, a WWW 
starting point tailor-made for your special needs. This will speed up data 
access as the browser then starts with a local file instead of going out on 
the network and lets you work much more efficiently since you can include 
pointers to your favorite WWW sites.

Like any WWW document, Home Pages are written in HTML. See the previous 
part of this introduction if you don't know what HTML is. The language 
elements described therein are sufficient for a simple HTML document. So, 
go ahead and create your own Home Page. Specify the title and heading of 
the document and include a list of hyperlinks to sites that provide the 
information you want to access often. (Some links that might be of interest 
for biologists have been provided in part 15 of this series of postings.) 
Save your document as "text only", then open it with your WWW browser and 
re-edit the source, if required. How to start WWW with your own Home Page 
depends on the browser software and operation system installed on your 
machine. The following descriptions apply to some of those browsers for 
which installation has been described in previous parts of this 
introduction:

*Lynx and NCSA Mosaic for X
On UNIX use the shell variable WWW_HOME to specify the URL of your Home 
Page. Add a line to the appropriate start-up file: 
  when running ksh:  export WWW_HOME=URL
  when running csh:  setenv WWW_HOME URL
On VMS use the logical name WWW_HOME to specify the URL of your Home Page. 
Add a line to the startup file or to the command file that invokes WWW:
  $ define "WWW_HOME" "URL"

*MacWeb
Start MacWeb. Select "Preferences..." from the "File" menu. Replace the URL 
of the default Home Page by the URL of your Home Page.
 
*NCSA Mosaic for the Macintosh
Start Mosaic. Select "Preferences..." from the "Options" menu. Then select 
"Misc" and replace the URL of the default Home Page by the URL of your Home 
Page.

*NCSA Mosaic for Windows
Quit Mosaic. Open the file "mosaic.ini" in the Windows directory. Replace 
the URL of the default Home Page by the URL of your Home Page.

*WinWeb
Quit WinWeb. Open the file "winweb.ini" in the Windows directory. Replace 
the URL of the default Home Page by the URL of your Home Page.

The WWW browser can handle only a restricted range of file types, but those 
files that cannot be handled internally are processed by so-called external 
viewers. The mapping of MIME types and file extensions to external viewers 
is configurable. MS-Windows browsers let you specify MIME types and file 
extensions in the appropriate "*.ini" file in the Windows directory. Using 
Lynx, the settings can be configured in the file "lynx.cfg" . MacWeb users 
can configure their browser by selecting the "Helpers..." and "Suffixes..." 
options in the "Edit" menu.

Most WWW browser provide various other parameters that can be configured. 
To change the default settings of these parameters:

* Lynx: type "o"
* MacWeb: select "Preferences" in the "File" menu.
* MacMosaic: select "Preferences..." in the "Options" menu.
* MS-Windows browsers: edit the "*.ini" file in the Windows directory.
* Mosaic for X: select the "Options" menu.

Go ahead and make changes according to your preferences.
