Read the cached static file information

 
  
  

  
   
   
< file  Act=info>web-inf/cache/page_test.html   file >   
 
  
  

Determine if a static file exists

 
 

  
  

  
< if   x= "@{file:exists}"else=0> 
  
  

  
 < Pager > page Call    >   
  
  

  
 < CALLXCALLX CALLXCALLX = true > Cache Call    >   
  
  

  
 if > 
 
 

exists on call to cache, does not exist then invokes page

 
  
  

  
   
   
< Pager > page Call    >   
  
   
   
< Pager  x=true>cachecall     >  
 
  
  

Callable Tag Cache , read cache file

 
 

  
  

  
< cHTML   onlycallid=cache> 
  
  

  
< file   Act= Read  method=str   name=page>web-inf/cache/page_test.html   file >   
  
  

  
 cHTML > 
 
 

Callable Tags Page

 
  
  

  
   
   
< cHTML  id=pagefile="@{sys:curpath} File_page.html "save=" web-inf/cache/page_test.html "  />
