+### Leakage of page existence by `do=goto`
+
+An unauthorized client can use a `do=goto` request to find out whether a
+page exists (will be forbidden to view it) or not (will be forbidden to create it).
+
+In [[plugins/contrib/signinview]] this is handled by hooking
+`cgi` first and checking for `goto` and a non-public page. If the requested page
+(existing or not) matches the `public_pages` PageSpec, it is handed off for the `goto`
+plugin to handle normally. Otherwise, the `do` parameter is changed to `signingoto`
+so the `goto` plugin's `cgi` hook will _not_ handle it, and the `sessioncgi` hook
+takes care of it when the user's identity is available.
