iis - How to configure static content cache per folder and extension in IIS7? -

i set rules in iis7 static content caching in asp.net website.

i have seen these articles, details how using <clientcache /> element in web.config:

client cache <clientcache> (iis.net)
add expires or cache control header static content in iis (stack overflow)

however, setting appears apply globally static content. there way directories or extensions?

for example, may have 2 directories need separate cache settings:

/static/images
/content/pdfs

is possible set rules sending cache headers (max-age, expires, etc) based on extensions , folder paths?

please note, must able via web.config because don't have access iis console.

you can set specific cache-headers whole folder in either root web.config:

<?xml version="1.0" encoding="utf-8"?> <configuration>   <!-- note use of 'location' tag specify         folder applies to-->   <location path="images">     <system.webserver>       <staticcontent>         <clientcache cachecontrolmode="usemaxage" cachecontrolmaxage="00:00:15" />       </staticcontent>     </system.webserver>   </location> </configuration> 

or can specify these in web.config file in content folder:

<?xml version="1.0" encoding="utf-8"?> <configuration>   <system.webserver>     <staticcontent>       <clientcache cachecontrolmode="usemaxage" cachecontrolmaxage="00:00:15" />     </staticcontent>   </system.webserver> </configuration> 

i'm not aware of built in mechanism target specific file types.
