That is correct for url encoding. You cannot have spaces in a query string. They have been replaced with %20 which is recognized as a space by the server when it receives the request.

Thanks for the points. &nbsp;Just as an aside, sometimes the blank can be URL-encoded into the plus sign, too. &nbsp;So <b>or 1 = 1</b> could look like <b>or+1+=+1</b> and it would likely work correctly, too.
