HTTP Response Header Lines

This section describes HTTP response header lines, which can be divided into three groups: General header lines, Response header lines, and Entity header lines.

HTTP/1.1 response header lines allows the server to pass additional information about the response which cannot be placed in the status line. Header lines can be divided into three groups:

1. General header lines: Information about the transmission of the entire response message:

   Cache-Control      
   Connection         
   Date               
   Pragma             
   Trailer            
   Transfer-Encoding  
   Upgrade            
   Via                
   Warning          

2. Response header lines: Information about the response:

   Accept-Ranges     
   Age               
   ETag              
   Location          
   Proxy-Authenticate
   Retry-After       
   Server            
   Vary              
   WWW-Authenticate

3. Entity header lines: Information about the data requested by the client:

   Allow              
   Content-Encoding   
   Content-Language   
   Content-Length     
   Content-Location   
   Content-MD5        
   Content-Range      
   Content-Type       
   Expires            
   Last-Modified
