That ratio may be a little high, but if you're going to be updating the 
data for each hit count and display count, that would definitely be a 
stretch for LDAP, especially if these attributes are indexed.

The fastest solution would be to store this information in memory, but 
that may not be an option.

PHP, Java, Perl, Tcl, C, and Python all apparently have strong support 
for LDAP. I always liked perldap, but I prefer to use Java for 
production applications. I use servlets (not JSP), and you can find out 
how at:

With Java there are (at least) 3 major libraries to choose from: JNDI, 
Netscape's JDK, and Novell's JDK. I don't want to start a flame thread 
here, but IMHO if you want security, efficiency, scalability, and 
reliability on the middle-tier, you should use Java or something like it.

Adam - sorry you didn't get this mail directly, but your address gave my 
mail server a relay error.
