Field Detail

• expires

  public java.util.Map expires

  This is a comma separated expiration mapping of the form: mimeType:seconds to expiry. This allows you to specify how long the browser is allowed to cache the file maching a given mime type from the time the file is originally served.

  For example, to set javascript files to expire in 1 hour and gif images to expire in 1 day: text/javascript:3600,image/gif:86400

  The comparison is an exact match of the specified mimeType against what the container returns for the intercepted URL. So, for example, if you specified text/javascript:3600 here, but the container was configured to return application/x-javascript for *.js (a common mimeType for javascript), then your expiry setting for *.js files would not apply.

• charsets

  public java.util.Map charsets

  This is a comma separated expiration mapping of the form: mimeType:charset This allows you to specify a character encoding for a given mimeType.

  For example, to set javascript files to be served with the UTF-8 encoding, set this value to: text/javascript:UTF-8

  For mimeTypes that do not have a charset specified, no charset setting is applied, so the container default is used.

  The comparison is an exact match of the specified mimeType against what the container returns for the intercepted URL. So, for example, if you specified text/javascript:UTF-8 here, but the container was configured to return application/x-javascript for *.js (a common mimeType for javascript), then your charset setting for *.js files would not apply.

• stripPathComponents

  public int stripPathComponents

  Instructs this servlet to remove the specified number of paths components from the URI before looking for the file on disk. This is useful if you're injecting a version string into your URI that isn't actually part of the path and you can't stript this off more efficiently at a different layer (e.g. Apache mod_rewrite).
