I was charmed to recently discover that Solaris 10 still hasn't fixedthat useradd issue I saw with Solaris 9 .For my future reference, since I am likely to wind up doing this a lot,here is how I add users on Solaris 10; this may or may not be theofficially approved way to work around the useradd issue.

An irony of conditional GET for dynamic websites
Ironically, dynamic websites are the least served by HTTP conditionalGET , because by the time they've worked outwhether or not a page's content is the same as what you've already got,they may well have generated the entire content.
