Walk through header data...

[cgm225]

I pulled this header data from firebug while looking at my website.  Can someone walk me through what it means, and if there is anything I can/should modify, and how?

For detailed 'decoding' I would suggest that you find the HTTP specifications and look through them.

 

The basics:

 

Raw HTTP headers (except for the first line), are like:

 

Key: value

 

So, for example

Content-Type: text/html

Would simply be saying to the browser, "Handle this like you would handle text/html"

 

 

"if there is anything I can/should modify, and how?"

 

 

All of it can be modified.  As for how, that would depend on your situation.  Why do you think you need to change it?
