(例子文件：_samples/file_page.html)

读缓存的静态文件信息

file act=info>WEB-INF/cache/page_test.htmlfile>  

判断静态文件是否存在

if x="@{file:exists}"else=0>   
    call>pagecall>   
    callxcallxcallxcallx=true>cachecall>   
if>   

存在就调用cache，不存在则调用page

call>pagecall>   
 call x=true>cachecall>   

可调用标签cache，读缓存文件

chtml onlycallid=cache>   
file act=read method=str name=page>WEB-INF/cache/page_test.htmlfile>   
chtml>   

可调用标签page

chtml id=page file="@{sys:curPath}file_page.html" save="WEB-INF/cache/page_test.html" onlycall />   

引入动态网页文件@{sys:curPath}file_page.html，并保存为WEB-INF/cache/page_test.html文件

显示缓存内容

@{file:page}

完整代码

html>   
chtml>   
file act=info>WEB-INF/cache/page_test.htmlfile>   
if x="@{file:exists}" else=0>   
    call>pagecall>   
    call x=true>cachecall>   
if>   
chtml>   
chtml id=page file="@{sys:curPath}file_page.html" save="WEB-INF/cache/page_test.html" onlycall />   
chtml onlycall id=cache>   
file act=read method=str name=page>WEB-INF/cache/page_test.htmlfile>   
chtml>@{file:page}   
html>
