If set to true, Smarty will respect the If-Modified-Since
header sent from the client. If the cached file timestamp has
not changed since the last visit, then a "304 Not Modified"
header will be sent instead of the content. This works only on
cached content without
{insert}
tags.
如果設(shè)置該變量為真,Smarty將分析客戶(hù)端發(fā)送來(lái)的If-Modified-Since頭信息.如果緩存文件時(shí)間戳自上次訪問(wèn)以來(lái)沒(méi)有改變,則發(fā)送一個(gè)"304 Not Modified"頭,而不是緩存文件內(nèi)容.這種方式僅工作于沒(méi)有
{insert}
標(biāo)記的緩存內(nèi)容.
