I have a web page with a dozen tables of data on it, each with half a dozen columns. Every table can be sorted by a column by clicking on the relevant header, and these get appended to the querystring.
e.g. a page with three tables sorted by column 4, 6, and descending 3:
I have nofollow links on the column headers, and
<link rel="canonical" href="page.html">
on the page.
But bing still crawls its way through thousands of combinations. 5772 of them yesterday!
I've marked s1/s2/s3/s4... as parameters to ignore (a long time ago), but that's not helped.
How can I prevent it from doing this? It's unnecessary server load for no gain.
