what is rand? - ASP.NET

Amelyan

Often, I see something called "rand" or ".rand" or "rnd" in url query
parameter, for example in yahoo mail url. E.g.

http://someurl.com/a.aspx?id=123&rand=91g3obstudb1r

or http://someurl.com/a.aspx?Rnd=1.2341123

What is it used for?

Thanks

Looks like some random string to avoid caching on browser.
I don't think it is something standard.

Anything that is in the querystring is just some variable or other than the
web developer is using for some purpose specific to the site they have
developed.

Could be a reference to Ayn Rand?
