For some reason my HTTP Host headers expires date is being set to “Expires: Mon, 26 Jul 1997 05:00:00 GMT” only on my Expression Engine sites? I have verified that other files in the same exact install directory have the correct expires value. It seems that the expression engine headers are not even being effected by the mod_expires ExpiresDefault parameter settings. The Date and Last-Modified-Dates are however correct. I have searched the forum and have not found any one else reporting this type of issue, hopefully someone will be able to help me out. Thanks!

EEDocs:// Output and Debugging Preferences

Take a look here at the docs.

Generate HTTP Page Headers?

This setting determines whether or not the server should automatically send HTTP page headers when it serves the pages to a user. Setting this preference to “Yes” causes headers to be explicitly sent by the server. Sending explicit headers is generally considered to be a good practice, although in some cases it can cause some problems.

What are you set to?

It’s set to “Yes”. Not sure why the date would be incorrect though?

ExpressionEngine sends the Expires header when header output is turned on; a date in the past ensures that browsers will always request new information for the page, so that your visitors do not see out-of-date content.  mod_expires is an Apache module, and does not affect the PHP code that ExpressionEngine uses to output its headers.

Thanks for the explanation, Derek.

Gotcha. Is there a reason why you would not want to show the old expires header?

I recall running into conflict once with some redirects, but that’s about it.  I turn it on by default- flip it off if I do run into an issue.  It’s rare that I do.
