It seems that you know more than you think you know. There are actually 3 methods, and not one. The main one doesn't work well with some of the proxies, and is probably exactly what you guessed. But it is noticeable immediately by the server. So then it can fallback to the other methods, one of them is specific to IE, and the other to Netscape/Mozilla (don't know about Konq/etc.). I don't speak about black-magics, but about popular tricks that are used by many respective companies (like ICQ - IIRC) Maybe somebody (I?) should start a SourceForge project to develop a library that will implement all these tricks, instead of the current situation when anybody has to re-invent the wheel. -- Eli Marmor [EMAIL PROTECTED] CTO, Founder Netmask (El-Mar) Internet Technologies Ltd. __________________________________________________________ Tel.: +972-9-766-1020 8 Yad-Harutzim St. Fax.: +972-9-766-1314 P.O.B. 7004 Mobile: +972-50-23-7338 Kfar-Saba 44641, Israel ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
