  8. //			display some server status via HTTP/HTML (there must be some
  9. //			uncommented lines in httpd.conf). However, the page sent to
  10. //			browser is a bit raw, completely unstyled, and hard to read.
  11. //			This script tries to make that page much prettier and more
  12. //			readable. It has been tested with Apache 2.0.55 and 2.2.21 and
  13. //			should work on most versions, unless the generated HTML changes,
  14. //			which will gradually degrade the script.

  90.   Instructions:
  91.   Download this file
  92.   Add <script src="sorttable.js"></script> to your HTML
  93.   Add class="sortable" to any table you'd like to make sortable
  94.   Click on the headers to sort
  95.   
  96.   Thanks to many, many people for contributions and suggestions.
