- Addendum to PCG3.TXT/DOC
- ------------------------
-
- We've now released gopher servers that use the gopher+ protocol
- specification, and the top-level gophers here are using this software.
- The gopher+ protocol includes several extensions to the base gopher
- protocol, referred to herein as gopher0. This version of PC Gopher III
- supports most of the gopher+ extensions, including Alternate Views of an
- item, and Item Attributes. Here's ho it works:
-
-
- Alternate Views
- ---------------
-
- Gopher+ servers may store multiple representations of one item. For
- example, an image of a gopher could be stored in GIF, TIFF, and
- PostScript formats, as GOPHER.GIF, GOPHER.TIF, and GOPHER.PS. These
- multiple representations of one object are called "Views".
-
- PC Gopher III will only show one entry in a menu for such an item;
- in the above example, the menu would show only
-
- <I> Gopher
-
- indicating that an image file called "Gopher" was available.
-
- To see what views of an item are available, choose "Alterate Views"
- from the file menu, or type Alt-V. PC Gopher III will query the
- server and put up a list of avaliable views for you to choose from.
- To download one of these views, double-click on it; you'll be
- prompted for a filename to save as, and PC Gopher will fetch the
- file.
-
- If you ask for alternate views of an item residing on a gopher0
- server, an error message will pop up reminding you that alternate
- views are only available from gopher+ servers.
-
-
- Item Attributes
- ---------------
-
- PC Gopher III can fetch files for you, but it can also fetch
- information about the files; for example, where the file you've
- selected resides, who the server administrator is, and so on.
-
- To view the attributes of an item, hilight it in the browser window,
- and choose "Item Attributes" from the file menu, or type Alt-I. If
- the item resides on a gopher+ server, PC GOpher will query the
- server and display the results in a window; if the server is a
- gopher0 server, PC Gopher will display what it knows about the item,
- but will not query the server; gopher0 servers don't know anything
- about item attributes other that their location, and PC Gopher
- already has that information.
