Domain-specific settings are stored in a $domain.tab file in 
/home/httpd/lonTabs/lonDomColors (replace $domain with the name of the 
domain e.g., msu.tab, sfu.tab etc.). 

When rendering pages for a specific domain, LON-CAPA will use any parameters 
defined within the domain's $domain.tab file in 
/home/httpd/lonTabs/lonDomColors to set colors and logos.  If a particular 
parameter has not been set in the domain's $domain.tab, then LON-CAPA will 
default to the value stored for the particular parameter in the default.tab 
file.  Hence the default.tab file contains a complete list of all the 
display parameters that can be set.  Typically a domain's $domain.tab file 
will include entries for only a small subset of these, and as a result will 
override the defaults for only a small number of parameters. 

The one exception to this is the domain logo itself which appears in the 
bottom left corner of the main (white) panel in the log-in page. In this 
case, when rendering the log-in page LON-CAPA does not consult the 
$domain.tab file, but instead will look in the directory: 
/home/httpd/html/adm/lonDomLogos for a $domain.gif file (e.g., msu.gif).  If 
a file is found it will be incorporated in the page, but if a $domain.gif 
file is not found, then text of the domain description will be displayed 

When a new domain.tab file is added for a domain in the LON-CAPA network, it 
should be checked into CVS, and a new entry added to loncapafiles.lpml so 
that it will be included as part of the LON-CAPA package that is used to 
install or update LON-CAPA on any server in the network. The same is true of 
any domain-specific images added to /home/httpd/html/adm/lonDomLogos 

e.g., msu.gif, headermsu.gif 

These should be added to CVS, and corresponding entries added to 
loncapafiles.lpml in CVS. 

The web server does not need to be restarted for these changes to take
