This tab is designed for Opera and Internet Explorer.

Internet Explorer (Max Connection Number Per Server) : The number of simultaneous requests to a single WWW server. According to standard HTTP protocol, browsers are not supposed to have more than two connections established to a single web site at one time.

Opera - Synchronous DNS Lookup : DNS (Domain Name System) is used to translate a Web address (for example www.opera.com) into an IP number such as 207.69.194.213. If the DNS server you are using is unable to look up more than one IP number at a time, you have to use synchronous DNS.

Note: If you are using Windows 95 with the Microsoft Winsock 2 upgrade, you MUST enable synchronous DNS in Opera's settings. Otherwise your connection will not behave properly.
