Voyager's Cache configuration is not fully functional yet but two of the On-Disk Cache options may be used.

• Maximum Size defines the largest size (in kilobytes) that Voyager's disk cache may grow to. Once it gets to this size, older documents are removed from the cache to make way for newer ones.

• Verify configures Voyager's cache verification. Voyager can check when you access a document that resides in its cache to see if it has been updated since your last access to it. If it has not been changed, it displayed the cached version. You can tell Voyager to verify the documents Once per session, Upon every access to the page, or Never (always use the cache).

3.58 Security

Voyager's Security functions are currently not accessible for you to configure.

3.59 Mail and News

Voyager currently supports mailto: links to send email to people on the net, and can access an NNTP news server to allow you to browse Usenet newsgroups. Here is where you can configure your identity to show the rest of the world.

• Your email address is required so that people can write back to you.

• Your Real Name is optional, but most people on the net prefer to know who they are conversing with.

• Organization is an optional field for anyone using Voyager within a business to fill in their company name for email/news.

• SMTP (mail) server and NNTP (news) are the servers which Voyager needs to talk to in order to send the mail or news that you have composed to the correct recipient. If you have any problems with these, your ISP should be able to help you.

• Telnet app defines an application to be launched when you click on a telnet: link within Voyager. %h sends the hostname in the link to the telnet application, and %p the port (if any). At Vaporware, of course, we recommend that you use AmTelnet %h %p.

3. 510 MIME Settings

The MIME GUI allows you to set "external viewers" to launch, run, play, view externally, view internally or save to disk, files on the Internet.

You need to tell Voyager what to do when it comes across certain files. For example, if someone had "click here to view this TIF file" how would Voyager show it normally? To view the file you would set a MIME type to recognise the TIF extension when it is encountered.

When you download a file, Voyager needs to know what to do - does it save to file, view it, play it etc. All files have MIME-types. For example a JPG file may have the MIME type of "image" and the sub-type of "JPG", which would normally look like "image/jpg".

Many of the preferences are already allocated for you (which you can change). An LHA file, for example, is already set to "save to file" as standard.

Setting the MIME Types - a .wav Example

The beauty of Voyager is that you can set the MIME types to recognise extensions such as a WAV sound file (normally found on a PC) or to play a AVI file (which is an animation file found on a PC or a MAC) when these are found within a web site.

To get Voyager to play a .wav file is relatively easy. First we need to get hold of the .wav datatype. Goto the section on the CD and extract the WAV datatype (ftWAV_dt40.2.lha). Install to the correct drawers on your Workbench.

WAV sound files have two different MIME types "audio/x-wav" and "audio/wav" so we need to make two entries within the MIME GUI to be completely secure.

1. Press Add New to create another MIME type.

2. Select the MIME Type as "audio" and the sub-type (the blank box to the right of MIME type) as "x-wav".

3. The Extension for a WAV file will be ".wav" so add wav into the blank extension box.

4. Change the Action to "use external application" and in the Application box below use the requestor to find Multiview (this is the program we will use to play the WAV file). Note the path needs to be complete. ie. it will look similar to "sys:utilities/multiview".

You should go through the same process again but change the MIME sub-type to "wav" instead of "x-wav". Press OK in the settings box and your prefs will be saved.

Voyager's MIME Pre-settings

Voyager understands and processes HTML and TXT (ASCII text) files internally and displays them within the main window. Voyager's internal image decoders also understand GIF and JPG and will also display these within the main window.

You can get Voyager to recognise other images but these would have to displayed outside the main window. Set your MIME-types to get Viewtek to show a TIF file, for example. Remember that you will need the relevant datatypes to do this!
