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

Question

I would like to set up rules in IIS7 for static content caching in my ASP NET website   I have seen these articles  which details how to do it using the  lt clientCache   gt  element in web config      Client Cache  lt clientCache gt   IIS NET    Add Expires or Cache Control Header to static content in IIS  Stack Overflow    However  this setting appears to apply globally to all static content  Is there a way to do this just for certain directories or extensions   For example  I may have two directories which need separate cache settings       static images    content pdfs   Is it possible to set up rules for sending cache headers  max-age  expires  etc  based on extensions and folder paths   Please note  I must be able to do this via web config because I don t have access to the IIS console

You can set specific cache-headers for a whole folder in either your root web config    lt  xml version  1 0  encoding  UTF-8   gt   lt configuration gt     lt  -- Note the use of the  location  tag to specify which         folder this applies to-- gt     lt location path  images  gt       lt system webServer gt         lt staticContent gt           lt clientCache cacheControlMode  UseMaxAge  cacheControlMaxAge  00 00 15    gt         lt  staticContent gt       lt  system webServer gt     lt  location gt   lt  configuration gt    Or you can specify these in a web config file in the content folder    lt  xml version  1 0  encoding  UTF-8   gt   lt configuration gt     lt system webServer gt       lt staticContent gt         lt clientCache cacheControlMode  UseMaxAge  cacheControlMaxAge  00 00 15    gt       lt  staticContent gt     lt  system webServer gt   lt  configuration gt    I m not aware of a built in mechanism to target specific file types

You can do it on a per file basis  Use the path attribute to include the filename   lt  xml version  1 0  encoding  UTF-8   gt   lt configuration gt       lt location path  YourFileNameHere xml  gt           lt system webServer gt               lt staticContent gt                   lt clientCache cacheControlMode  DisableCache    gt               lt  staticContent gt           lt  system webServer gt       lt  location gt   lt  configuration gt
