Nginx反向代理與服務(wù)器的配置緩沖
Nginx反向代理關(guān)于對后端服務(wù)器的配置。對于廣大的網(wǎng)管員來說nginx反向代理是必修的一門課。下面我們就來看看有關(guān)的內(nèi)容。有三個后端服務(wù)，一個為web內(nèi)容服務(wù)，一個是論壇服務(wù)，一個為文件服務(wù)。
當(dāng)一個請求來時，nginx代理服務(wù)器其查看url把請求定向到相應(yīng)的服務(wù)器，這個配置也緩沖文件服務(wù)的內(nèi)容，但是論壇的和數(shù)據(jù)下載的內(nèi)容就不緩存了，這個配置也使用了壓縮，更好的節(jié)省內(nèi)存
