ETag header not being sent from PHP

I'm running PHP 5.3.2 and Apache 2.2.14. Using header(), If I send "ETagx" I get the header in the response, but if I send "ETag", the correct header name, I get nothing.

header('ETagx: "33653a-4831d8249af80"')

works, while

header('ETag: "33653a-4831d8249af80"')

does not. Is there a configuration option in php.ini, or in any of the Apache configuration files that might affect this?

I replicated this situation when I had Charles HTTP Proxy active with the 'No Caching' option enabled - the HTTP proxy was removing the ETag and other cache-related headers. If using a proxy to view the headers, ensure that caching is enabled for the specific request.

Just tested on PHP 5.3 and Apache 2.4 and it worked for me.

Make sure that Apache don't unset your Etag like this:

<IfModule mod_headers.c>
  Header unset ETag
</IfModule>

FileETag None
