I have a line of code that I borrowed from another script to read the 7.html page from shoutcast.
Code: Select all
puts -nonewline $lcl_StreamWebPageScoket "GET /7.html HTTP/1.1\nAccept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-sh
ockwave-flash, */*\nAccept-Language: en-us\nAccept-Encoding: gzip, deflate\nUser-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; T312461; (R1 1.3); .NE
T CLR 1.0.3705; .NET CLR 1.1.4322)\nHost: www.awesomechat.net\nConnection: Keep-Alive\n\n"
But I have no idea what it means other then it puts a line as if it was a browser???? But, the rest of that stuff???? I have no idea.
Can anyone explain to me why this would be done like this?

Thats the older method using the tcl socket code to retrieve webpages manually. Obviously the person who wrote the original script knew exactly what they needed to access a particular webpage in this way..Most(?) of us nowdays use the tcl http package, because it simplifies things a bit especially with more complicated web pages requiring queries and such.
The Accept- lines are http header directives. Refer to the relevant htt-protocol specs, eg:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
