Change GSA proxy check frequency

Is this possible?, what is the default duration for it checking public proxies?

When you click the configure button for proxies in the option menu, a window will pop up and if you look at the top of the window you'll see two buttons, click the "options" button and you can tweak the frequency.

Hi thanks for the response, is the interval test carried out after the search then?, cant just test in isolation until the working volume < N?, then look for a new bunch

Test and search take the same interval.
