Varnish在不同的瀏覽器上行爲不同，爲什麼？

Question

在Firefox上，Varnish正在發揮作用，但不在Google Chrome上。可能？爲什麼？

Answer 1

一個可能的原因可能是，你必須在Chrome瀏覽器會話cookie，導致光油將請求傳遞到後端。

Answer 2

最可能的原因是Accept-Encoding頭的標準化，Firefox和Chrome傳送不同的一個。添加到您的子vcl_recv（）：

if (req.http.Accept-Encoding) { 
    if (req.url ~ "\.(jpg|png|gif|gz|tgz|bz2|tbz|mp3|ogg)$") { 
     # No point in compressing these 
     remove req.http.Accept-Encoding; 
    } elsif (req.http.Accept-Encoding ~ "gzip") { 
     set req.http.Accept-Encoding = "gzip"; 
    } elsif (req.http.Accept-Encoding ~ "deflate") { 
     set req.http.Accept-Encoding = "deflate"; 
    } else { 
     # unkown algorithm 
     remove req.http.Accept-Encoding; 
    } 
} 

這也記錄在Varnish manual on the "Vary" header。其他

Answer 3

if (req.http.Accept-Encoding) { 
     if (req.http.Accept-Encoding ~ "gzip") { 
      set req.http.Accept-Encoding = "gzip"; 
     } elsif (req.http.Accept-Encoding ~ "deflate") { 
      set req.http.Accept-Encoding = "deflate"; 
     } else { 
      # unknown language. Remove the accept-language header and 
      # use the backend default. 
      unset req.http.Accept-Encoding; 
     } 
    } 
    //add below condition along with above code in vcl_recv subroutine. 
    if(req.http.User-Agent) { 
     unset req.http.User-Agent; 
    }
