A ja by som chcel, aby si sa konečne začal zrozumiteľne vyjadrovať.
Ak prístupom na web myslíš prístup k PHP/HTML alebo iným súborom, dá sa to bez databázy, pomocou súboru .htaccess (ak máš na servri Apache). Už sa to tu milión krát riešilo, tak hľadaj.

The terms LF, MF, and HF refer to low, medium, and high frequency, respectively. Clearly, when the names were assigned, nobody expected to go above 10 MHz, so the higher bands were later named the Very, Ultra, Super, Extremely, and Tremendously High Frequency bands. Beyond that there are no names, but Incredibly, Astonishingly, and Prodigiously high frequency (IHF, AHF, and PHF) would sound nice.
