Sorry, this is a little off-topic, and not completely original, but interesting (at least to me) nonetheless.

I've done something similar to this: make a dynamic site appear static for the purpose of search engine indexing.

The way I did it was with the creation of each item, output an SSI statement into a file with proper parameters to call the dynamic content:
Example: I have a directory called "/redir/" that has all my SSI files in it. Each file is tiny, and looks something like this:
<!--#include virtual="/cgi-bin/process.pl?action=viewitem&id=97"--> Then each link on my site calls this SSI directive with the name "/redir/97.html". All the links look static but are created when requested because of the SSI trickery.

The "caught in an infinite indexing loop" is important to think about, I don't know how it would be handled on the perlmonks site.

Obviously google does index some dynamic content, as evidenced by jeffa's search above. Do we know how google decides what dynamic content to index? This whole point may be moot.

    [davido]: or on ubuntu /var/run/utmp
    [Corion]: Otherwise, I would imagine that a user with a process still alive would lock that information in memory.
    [davido]: so last -f /var/run/utmp on ubuntu provides similar (though more verbose) info
    [oiskuu]: glibc getlogin just does ttyname() and falls back on getutline(); it's not security related at all. (reminds me of sendmail and remote finger services of the naive early spam era)
    [Corion]: But yes, "who started this process" is interesting information :)
    [tye]: no, I really believe that "login user" was added as a fundamental bit of info about each process in order to enhance the usefulness of auditing
    [Corion]: Ah - if that information is saved in a file, then you could theoretically spam that file and confuse getlogin(). So, don't use it for authentication :)
    [tye]: that is what getlogin() certainly *used* to do. I don't believe that is what it certainly should do.
    [davido]: /var/run/utmp is 664 i think.
    [tye]: Note that my "man getlogin" says that it uses stdin when it should use /dev/tty (calling a glibc bug). But that does not appear to be the case when I test it. But maybe Perl's getlogin() is not using glibc's getlogin().
