Yves, James, I can see your reasoning, the page has expired a long time ago! This meta header is used to tell the browser how to cache this document. In this case, cache until 2000-01-01, or don't cache at all. This is the most powerful way we have found of forcing a browser not to cache the CGI. Some browsers (MSIE v4) can be fanatical about caching, which makes life for a CGI coder very hard. Eg, having to add random numbers into every URL, ugh! There would be a large number of web sites which would fail to work if this had other implications. But maybe in the future a more dynamic date should be used. However, to keep an open mind, there is no harm in trying to alter this. Line 365 in perfgraph.c, try a more recent date: Expires: Sat, 01 Jan 2005 01:01:01 GMT It would be interesting to see if this did effect the code?
