我最近使用 CFCACHE 在冷融合 9 服务器上实现页面缓存。
但是我在负载下报告错误(运行自动链接检查器),例如:“缓存 A95C0BF9E9BFBC6F151F03E939D2D2D6TEMPLATE 已经存在”
我曾认为 cfcache 将是线程安全的,并且无需任何额外代码即可处理此问题。如果它是相关的,我会在我的 application.cfc 中的“OnRequest”中调用它。对我来说,这似乎是一个 Cold Fusion 错误,但我也有可能以某种方式滥用 CFCACHE 机制。
<!--- setup caching if enabled --->
<cfif getConfigValue('page_cache') eq "true" and not application.security.isLoggedOn()>
<cfcache timespan="#createTimeSpan(0,0,10,0)#" directory="#application.pagecachepath#" usequerystring="true" >
</cfif>
<!--- Call request handling and rendering functions --->
<cfcontent reset="yes" type="text/html"><cfoutput>#html.render()#</cfoutput>
<cfif getConfigValue('page_cache') eq "true" and not application.security.isLoggedOn()><!-- content generated at #Now()#--></cfif>
堆栈跟踪是:

如果没有更好的想法,我想我会开始研究 EH 缓存源!
