Mosaic Version 2.7b1

Improvements

• Kerb 4 and Kerb 5 Authentication -- At present we have not been able to compile the kerb libs on all platforms. Hopefully, this will be alleviated sometime soon. Remember you must be a registered user in the realm you are trying to access to use kerberos. The breakdown is as follows:

   
  	Platform - Kerberos 4 - Kerberos 5 
  	Alpha         No           Yes 
  	Dec           No           No 
  	Hp            No           No 
  	Ibm           No           No 
  	Indy          No           No 
  	Linux         No           Yes  
  	Sgi           No           No 
  	Solaris-2.3   No           No 
  	Solaris-2.4   No           No 
  	Sun           Yes          Yes 
  

  As you can see, kerberos has not been an easy thing to compile on our supported platforms. If anyone has suggestions for compiling on one of the above platforms, please bend our ear! The X resource "Mosaic*useAFSKlog: False" allows you to login for a ticket granting ticket via AFS klog instead of kerberos login functions.
  If Kerberos is compiled into your binary, you will be able to login in for your ticket granting ticket anytime you wish (although the process is automatic if there is a problem with your TGT) through the "File | Kerberos * Login".
  

• MD5 Authentication -- Compiled and working on all platforms.
• Security Icon -- New icon to visually let the user know what type of authentication is being used. You _can_ click the icon and get more information about the authentication in use. The X resource "Mosaic*securityIcon: True" will turn on or off this feature.
• Source modification date is now available for almost all documents served from a httpd server. "File | Source Date..." will get you there.
• Postscript printing has changed! A patch was integrated and improved upon which allows for several new things:
  • A4 or US paper size! The X resource "Mosaic*printPaperSizeUS: True" allows you to specify a default.
  • A header label which consists of the actual document title and the page number on the right. The X resource "Mosaic*printHeader: True" gives you the option of having this on or off by default.
  • A footer label which consists of the actual URL and last modification date of the document. Above this footer label is a footnote list of all the anchors appearing on the current printed page (these anchors have super-script numbers by them). The X resource "Mosaic*printFooter: True" gives you the option of having this on or off by default.
• Extension Headers -- Extension headers are now handled. At present we only support one from the server (Extension: Domain-Restricted) and one that we send to the server (Extension: Notify-Domain-Restriction). These are used to support the "domain authentication" icon.
• CCI Calls -- Lots of new ones. There will be a revision of the CCI html page soon.
• FTP -- Ftp now keeps its connection open for multiple transactions as well as giving you the info messages for each directory change and login. This is a huge improvement over dropping connection between each transaction, especially on a busy server. There is an X resource "Mosaic*ftpTimeoutVal: 90" which allows you to set the number of seconds before your ftp connection times out.
• Keep-Alive -- Keep-Alive connections are in effect! Keep-Alive is a new header passed to NCSA httpd-beta-1.5 (at present this is the only _known_ server that supports this feature, please correct us if we are wrong!) which will hold the connection open for a server-set timeout and server-set transaction limit. This allows for a noticable speed-up on long-distance connections as the overhead of closing and opening connections with the server are eliminated. Please note that you must be getting service from a server that not only supports the Keep-Alive functionality, but has it configured to be used. The X resource "Mosaic*useKeepAlive: True" allows you to turn on or off this functionality.
• Portable Network Graphics (PNG) -- PNG is now a valid in-line image format. At present, there are some color problems with PNG images that do not have their own pallette stored and there are some dithering mosquitoes to be swatted, but the majority of images you will find on the net will display just fine. However, we are most certainly open to improvement suggestions.
• Hold onto your firewalls...no_proxy -- Yes, we finally integrated the now infamous "no_proxy" patch!
