Aggressive Caching: Do All Browsers Support URL Parameter for Updating?

After further research, it turns out that some proxy caching services will not cache files with query strings in the URL. Whether this is true for some web browsers, I don't know.

The only way a browser could not "support" query-parameter controlled caching is if the browser used the cached version retrieved using a different parameter value. I have never heard of a browser that did that. So yes, all browsers support this technique.

The only disadvantage I can think of is that you can't host multiple versions of the resource simultaneously. (assuming you are using static files).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
