這裏是請求頭:Firefox重新加載緩存的PHP腳本。如何防止這種行爲?
GET /url/ HTTP/1.1
Host: example.com
User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: ru-RU,ru;q=0.8,en-US;q=0.5,en;q=0.3
Accept-Encoding: gzip, deflate
DNT: 1
Cookie: data=ABC;
Connection: keep-alive
Cache-Control: max-age=0
這裏是來自服務器的響應:
HTTP/1.1 200 OK
Date: Fri, 11 Oct 2013 23:28:32 GMT
Server: Apache/2.2.14 (Ubuntu)
X-Powered-By: PHP/5.3.2-1ubuntu4.18
Expires: Wed, 16 Oct 2013 03:28:32 GMT
Cache-Control: max-age=360000
Pragma: cache
Content-Language: en
Vary: Accept-Encoding
Content-Encoding: gzip
Content-Length: 844
Keep-Alive: timeout=15, max=92
Connection: Keep-Alive
無論多少次,我刷新頁面,不管如何,它總是讓一個請求(由於它是HTTPS,因此需要200ms以上)。我在監督什麼?響應頭文件是否包含更多參數以防止Firefox發出服務器請求?
