In web-client how to do autocomplete addresses no from Contacts

[Chai]

Hi!
We uses web-clients for mail and there is autocomplete in field "To" addresses from Contacts.
But other addresses which was typed previously for mails is no autocompleted.
How to make that other addresses too were found and substituted?

Thanks!!!
