    The delay in loading is due to at least 9 perl scripts getting triggered - see also [ Perl Notes (live) ]
    clicking "perl: " line shows the source ....... clicking "out: " line runs the CGI script
    1.Env
    - why: display $ENV variables from HTML page
    - perl: env.cgi
    - in: /cgi-bin/pub/env.cgi?my_query_string_here&a=1&b=2
    - out: run env.cgi

    3.Display Perl
    - why: code/HTML/text displayed in HTML
    - perl: display.cgi
    - in: /cgi-bin/pub/display.cgi?/cgi-bin/pub/env.cgi
    - out: run display.cgi

    5.Hit Counterabout
    - why: displays web-page hit counter (GIF or x-bitmap)
    - perl: counterc.cgi
    - in1: /cgi-bin/pub/counterc.cgi?123
    - in2: /cgi-bin/pub/ccounterc.cgi?123&TYPE=gif
    - out1: run counterc.cgi (X-bitmap)
    - out2: run counterc.cgi (GIF)
    7.File Not Foundabout
    - why: redirect on file-not-found
    - perl: file-not-foundc.cgi + fnf.pm
    - in: /cgi-bin/pub/file-not-foundc.cgi?
    http://www.robertbody.com/where-is/my-/arizona.html
    - out: run file-not-foundc.cgi
    9.My Calendar
    - why: days listing for any year 1 .. 9999
    - perl: fmycal.cgi + rbh.pm
    - in: /cgi-bin/pub/fmycal.cgi
    - out: run fmycal.cgi
    11.Pictures Count
    - why: scans my website for # of pictures in each group
    - perl: wc.cgi
    - in: /cgi-bin/pub/www/wc.cgi
    - out: see webstats or if you insist, run wc.cgi
    - note: total time is typically 0 seconds...
    therefore a count to 3,000,000 is done afterwards
    2.Arizona Time
    - why: display current time
    - perl: date.cgi
    - in: /cgi-bin/pub/mydate.cgi
    - out: run date.cgi?state=az

    4.X-bitmap counter
    - why: returns X-bitmap (a picture) in HTML
    - perl: bitmap.pl
    - in: /cgi-bin/pub/bitmap.pl?1234&5
    Count (max 10 digits) & Minimum Length
    - out: run bitmap.pl - doesn't work in new IE
    6.GIF counter
    - why: displays web-page hit counter
    - perl: gifc.cgi
    - in: /cgi-bin/pub/gifc.cgi?1234
    - out: run gifc.cgi

    8.Who am i
    - why: info about You
    - perl: who.cgi
    - in: /cgi-bin/pub/who.cgi
    - out: run who.cgi
    10.Word Scrambler
    - why: Mseess up words, but you can sitll raed ok
    - perl: m1.cgi
    - in: /cgi-bin/pub/m1.cgi
    - out: run m1.cgi (via my Popup Manager)
    12.GMT Play
    - why: playing with current time, GMT and others
    (now duplicated with date.cgi?gmt)
    - perl: gmt-play.cgi
    - in: /cgi-bin/pub/gmt-play.cgi
    - out: run gmt-play.cgi

    (gmtime.cgi)
    Note that scripts ending in "c", such as counterc.cgi and file-not-foundc.cgi
    are copies of the originals used by my website and may not have all the latest changes.


    Input
    - why: read CGI type input
    - perl: input.pl
    - in: /cgi-bin/input.pl?a=123&b=456&c=789&d=482
    - out:
    req=GET--------------------
    orig: a=123&b=456&c=789&d=482
    $in[0]: a=123
    $in[1]: b=456
    $in[2]: c=789
    $in[3]: d=482
    in[a] => 123
    in[b] => 456
    in[c] => 789
    in[z] =>
    a => 123
    b => 456
    c => 789
    d => 482

    about Hit Counter
    counterc.cgi is my most complex perl script here. It is trigged by HTML page loading, and handles the following:

    • updating a different hit counter value for each webpage, using
    -- JavaScript document.write for GIF images

    • concurrent access to same page is handled by file-locking, 1 second delay, and 5 retries

    • logging is done for (refer to output below):
    1. current hit counter value
    2. access time,
    3. user ip,
    4. file ID (of current page visited) and
    5. the page referrer (where the page was accessed from -- Yahoo search, etc).

    _4248  Thu Sep 25 11:54:04    205.188.208.8  _index 
    This shows
    4248 hits, when user IP 205.188.208.8, was at main page (_index) without referrer (typed in the name), and
    2871 hits, when user IP 66.255.61.139 came to my Metric Conversions page from web.ask.com.

    nslookup 205.188.208.8
    yields
    cache-da04.proxy.aol.com
    as the servername

    the page referrer in the last column is truncated for readibility from something like:
    http://web.ask.com/redir?bpg=http%3a%2f%2fweb.ask.com
    %2fweb%3fq%3dhow%2bmany%2bfeet%2bare%2bin%2ba%2bmile%253f%26o%3d0%26page%3d1
    which translates to someone typing in "how many feet are in a mile" at http://web.ask.com
    (The answer to which can be found at the targetted page --> Metric Conversions )

    about File Not Found
    My file-not-foundc.cgi handles bad links from search engines, etc (because i have no bad links of my own :)). As a bonus it allows quickly getting somewhere, for example by changing the end to be "/map" in http://www.robertbody.com/somewhere/anywhere/map

    When you click on the link, a redirect attempt occurs, matching on
    (1) filename.ext (if any), else on filename (if any), or otherwise
    (2) directory name, or lastly
    (3) matching on a special string (eg. funny_pictures) anywhere in the path

    The lookup is via hash-table, and (3) becomes the last chance of matching.
    Currently [2003-10-05], while
    (1) and (2) have 65 options, with match duplicates (eg. scrambler and mess trigger Word Scrambler)
    (3) only has 2 entries, and may max out at 5 one day.

    By clicking
    file-not-foundc.cgi?http://www.robertbody.com/where-is/my-/arizona.html
    and wrapping JavaScript around it, the found page is loaded.
