I can see that there are avantages to putting parameters into POST data. Are there any advantages to a bot putting parameters into the URL?
The only advantage I can think of is caching. If you're repeating the same request a number of times and want any caching proxies between you and the server (e.g. Wikimedia's Squid servers) to cache the result for you, you can put &smaxage=3600 (or any number of seconds) in the URL. This only works for GET requests and only when the URLs are exactly the same both times.
