As I understand, this mid-handler is your responsehandler that subsequently
makes a call to the generic responsehandler of ajax.js. So it is not a real
custom handler (that requests + handles response independent of the generic
one)

Also, as I understand from your code, the proposed console would store a
log of run queries and on running a query from console, the results will be
displayed in the same way as happens when running a query from SQL tab.
Right ?

As per this understanding, you need a real custom handler because executing
SQL and handling its response in PMA involves many custom checks and calls
not only at response stage but also at request stage. For ex:-
- checkSqlQuery()
- bookmark handling
- reloading navigation for certain queries
- refreshing main panel for certain queries
- triggering grid edit for results
 etc. see in sql.js near  $("#sqlqueryform.ajax").live('submit', function
(event) {

Or did you plan to duplicate above checks and calls into your midhandler?

Also, I don't understand why you need to call the generic response-handler
of ajax.js? Remember that we don't need to populate AJAX.cache either.

Yes, you need to totally skip the generc/global AJAX handlers, for that you
add a "class=ajax" to your form and write a custom handler.
