Google will sometimes index pages with querystring parameters. The algo Google uses to determine whether to index url's of this type is unknown, but much speculated upon ;-)
In my experience, Google may index mypage.cgi?t=1 if the site has a reasonable PageRank (inward links) but will not follow any links with querystring parameters from that dynamic page. So if mypage.cgi?a=1 links to another page mypage.cgi?a=2, this 2nd page isn't indexed. WebmasterWorld Google Knowledgebase V2: "Q: Does Google index dynamic content? A: It will in certain instances..." http://www.webmasterworld.com/forum3/2829.htm#item355 Google Webmaster Guidelines: "If you decide to use dynamic pages (i.e., the URL contains a '?' character), be aware that not every search engine spider crawls dynamic pages as well as static pages. It helps to keep the parameters short and the number of them small.
