Expire headers

[NeoCHI]

My host (knownhost) just added:

## EXPIRES CACHING ##

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
ExpiresDefault "access plus 2 days"
</IfModule>

## EXPIRES CACHING ##

# Enable expirations
ExpiresActive On
# Default directive
ExpiresDefault "access plus 1 month"
# My favicon
ExpiresByType image/x-icon "access plus 1 year"
# Images
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"

# CSS
ExpiresByType text/css "access 1 month"

# Javascript
ExpiresByType application/javascript "access plus 1 year"

for me, but I think this is causing issues for my site. New threads and posts are loading unless the user does a hard refresh...

I'm especially suspicious of:

ExpiresDefault "access plus 2 days"

That ExpiresDefault would be causing browsers to cache everything without an explicit cache statement for 2 days. That includes the forums, threads, etc.

 

[NeoCHI]

That's what I assumed.....I even told my technician at my hosting service that that line they added for me seems highly suspicious and he kept saying it's only for images/css. Freaking idiot! I forgive the person who added it since he may not have known my site was a forum but not the guy I specifically told him what the issue was and he still denied it....

Knownhost support get your crap together!

 

[NeoCHI]

Btw, can someone show what I SHOULD use for expire headers? Also do I just need to put it into my .htaccess for it to work?

 

[NeoCHI]

No one? I'm assuming it's actually what my server added for me but just without the "ExpiresDefault" so:

## EXPIRES CACHING ##

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access plus 1 year"
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType text/x-javascript "access plus 1 month"
ExpiresByType application/x-shockwave-flash "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
</IfModule>

## EXPIRES CACHING ##

# Enable expirations
ExpiresActive On
# My favicon
ExpiresByType image/x-icon "access plus 1 year"
# Images
ExpiresByType image/gif "access plus 1 month"
ExpiresByType image/png "access plus 1 month"
ExpiresByType image/jpg "access plus 1 month"
ExpiresByType image/jpeg "access plus 1 month"

# CSS
ExpiresByType text/css "access 1 month"

# Javascript
ExpiresByType application/javascript "access plus 1 year"

Is this ok?
