Apparently because of some user complains about wierd behavior when using The Google Accelerator, the old When to use GET document has become popular. The idea is in a web page to use <a href=.. whenever the operation is “safe” and to use <form action=post… whenever the action is “unsafe”. A classic unsafe operation is, say, deleting a record from a database – it can’t be invoked twice, and you don’t want the browser or some other caching system to speculatively fetch such a URL.

Well the design flaw is, how come with <a> you can’t specify that you want to use POST instead of GET? With <form> you can say <form action=post or <form action=get—now how come you can’t say <a action=POST href=…>…<a>? It seems logical and orthogonal doesn’t it?
