HOWTO: Controlling Caching of HTTPS content

Expand / Collapse

This article applies to:

  • WebMarshal 7.5.5 and above
  • Proxy caching

Question:

  • How do I control caching of HTTPS content?

Background:

WebMarshal 7.5.5 and above caches static files delivered over HTTPS by default.
  • This is a change from earlier versions that did not cache HTTPS content. This change reflects the reality that most reputable websites now use HTTPS for most content.
  • Static files generally include scripts, images, and other helper files that do not contain sensitive content.
  • HTTPS caching is only active for inspected HTTPS content. If your policy excludes a site from inspection, the content from the site will not be cached.

Procedure

To disable caching of HTTPS content:

  1. Add the following entry to the WebMarshal Proxy Configuration file (WMProxy.config.xml) on each processing server
    2. <WebMarshal>
       <Proxy>
         <Config>
            <Cache allowHTTPSCaching="false" />
         </Config>
      </Proxy>
    </WebMarshal>
  2. Restart the WebMarshal Proxy service.

Note

  • WMProxy.config.xml will include other entries. Do not change the other entries.
  • The Cache element may exist and contain other attributes. Add the new attribute to the existing element.
  • XML files are case sensitive.
  • For general information about editing XML settings files, see article Q12705.
