+ Alternate Interval Syntax +

+

+ The + ExpiresDefault + and + ExpiresByType + directives can also be defined in a more readable syntax of the form: +

+
+
ExpiresDefault "<base> [plus] {<num> <type>}*" +
+ ExpiresByType type/encoding "<base> [plus] {<num> <type>}*" +
+
+

+ where <base> is one of: +

+ +
  • access +
    • +
  • now (equivalent to 'access') +
    • +
  • modification +
    • +     +

    +

    + The 'plus' keyword is optional. <num> should be an + integer value [acceptable to atoi()], and <type> + is one of: +

    + +
  • years +
    • +
  • months +
    • +
  • weeks +
    • +
  • days +
    • +
  • hours +
    • +
  • minutes +
    • +
  • seconds +
    • +     +

    + For example, any of the following directives can be used to make + documents expire 1 month after being accessed, by default: +

    +
    +
    ExpiresDefault "access plus 1 month" +
    + ExpiresDefault "access plus 4 weeks" +
    + ExpiresDefault "access plus 30 days" +
    +
    +

    + The expiry time can be fine-tuned by adding several '<num> <type>' + clauses:

    +
    +
    ExpiresByType text/html "access plus 1 month 15 days 2 hours" +
    + ExpiresByType image/gif "modification plus 5 hours 3 minutes" +
