Can anyone enlighten me on the following question:

What do different fields in accept field in HTTP request mean? I can understand the basics that through accept the client is telling the server what type of information it is waiting to receive, so for example:

Accept:text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

This way the client will tell the server that it can understand three following formats:

text/html
application/xhtml+xml
application/xml

But can someone tell me what this q values mean and that /

Also if I have any flaws in my understanding - please tell me.
