1.網頁壓縮
2.網頁緩存javascript
1.配置防盜鏈
2.隱藏版本信息php
配置網頁壓縮功能
工做模式的選擇與參數優化
配置防盜鏈
配置隱藏版本號css
1.下降了網絡傳輸的字節數,加快網頁加載的速度
2.節省流量,改善用戶的瀏覽體驗
3.gzip與搜索弓|擎的抓取工具備着更好的關係html
1.mod_gzip模塊
2.mod_deflate 模塊java
1.沒有內建網頁壓縮技術,但可以使用第三方mod_ mysql
1.在開發的時候,內建了mod_deflate 這個模塊,取代mod_gzipc++
1.二者均使用gzip壓縮算法,運做原理相似
2.mod_deflate 壓縮速度略快,而mod_gzip 的壓縮比略高
3.mod_gzip 對服務器CPU的佔用要高一些
4.高流量的服務器,使用mod_deflate 可能會比mod_gzip 加載速度更快算法
1.執行apachectl -t -D DUMP MODULES命令
2.若是輸出中沒有deflate module (static),說明編譯時沒有安裝
mod_ deflate模塊sql
1../configure --enable-deflate...
2.make && make installapache
1.AddOutputFilterByType DEFL ATE text/html text/plain text/css
text/xml textjavascript
2.DeflateCompressionL evel
3.SetOutputFilter DEFL .ATE

輸入對方的IP地址以後能夠看到添加的圖片,咱們經過抓包軟件能夠看到有圖片的抓取信息中有在端口處進行gzip壓縮處理信息
