My Linux space of IXWebHosting, the free hostings which GoDaddy presented to me, and a domestic Linux space, all of them do not support the mod_expires module. At present, the newer version of Apache is 2.2.*, such as 2.2.14, this version contains the mod_expires module, but the default does not turn on this module, in the default httpd.conf file, there is a # symbol before the sentence which loads the mod_expires module. But the Linux hosting of GoDaddy, use the Apache 1.3 version all the same.

I posted an Email to GoDaddy yesterday, hope to turn on the mod_expires module, I've just received the reply of GoDaddy, they said that they do not want to turn on this module now, maybe this clerk did not know the important action of the mod_expires module. It seems that if need use the mod_expires module, just can use the others hosting of provider, or VPS.

I've downloaded the Apache 2.2.14 version, tested on the local computer, the mod_expires module can be used normally.
