Warnings

It's a little too bad there's no way to avoid a warning when the variable we're fetching is not set ...

  You only recieve a warning? I get see an error. Most annoying!

    using 3.7.4 and getting an error as well. even testing for the existence fo a get/post var throws an error:
    {if ezhttp( 'myvar', 'get' ) } => returns false, but throws error
    the same with {if is_set( ezhttp( 'myvar', 'get' ) )}
    its a bug in my opinion..

  you can use in 3.9 (trunk) like:
  ezhttp_hasvariable( 'getVar','get' )
  or
  ezhttp( 'getVar','get','hasVariable' )
Why not ?

It would be nice if the ezhttp operator could return all vars in the array specified. ezhttp(GET) would return all $_GET vars for example.

  You actually can get all the $_GET variables, or $_POST.
  {def $foobar=ezhttp()}
  This brings you all the http variables, be them get, post or session, in an array. You can check them out doing:
  {$foobar|attribute(show)}
ezhttp is not working if caching is turned on.

i put
{set-block scope=root variable=cache_ttl}0{/set-block}
to all templates, because in other way ezhttp will return the same value...
or null

Returns:
Variable value or null
test for non-existence using
{if not(ezhttp('test'))}
or
{if ezhttp('test')|null()}
