As to why they do this, remember that caching is good for you, but bad for the advertisers. There are many tricks used by sites to encourage "cache-busting." This is not a bad thing, but simply a reality - the site wants you to download (and hopefully view :) as many banners as possible. More pageviews = more $$$ from the advertisers.

If it really bothers you (even if just from one slow location) you could install the Internet Junkbuster software, which lets you selectively block banners (along with lots of other useful features, e.g. cookie control) If you do go that route, buy something from the Buy Stuff page to appease your guilty conscious. :)

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
