session handling and W3TC

The cookie handling has not changed.

The only change is using a custom table rather than the options table.

Thanks for quick reply. Greenwatersports.com/shop is the domain, add a product and navigate back and forth to cart, does the message stay at the top. What would be causing this? (the minicart drop down at top right “visit shop” used to update to “secure checkout” after you added something to cart…) same issue?

Are you sure its excluded? The content is minified.

Mike can you confirm do we actually need to change our W3 Total Cache settings for 2.5 or no? I have several dozen sites running WC + W3TC so this could be a major problem if so. Thanks!

Hi Mike,

Can I confirm what is excluded? the cart page from page cache, cookies, query stems? All i know it was working before. I am testing as we speak and will try to turn off all DB caching to test.

Since woocommerce_sessions is the name of the table that added as a query stem should be enough.

Regardless, the notice is only displayed after the EVENT of adding to cart. So it looks like the HTML is being cached, not the database query.

I thought Woocommerce had NOCACHE for cart and checkout pages built in, regardless of me using or adding it to NOCACHE in w3tc? Did the notice stay for you beyond “after the event”?

it did.

And yes, it does set nocache, however it can be ignored if caching occurs at a higher level.

This did not happen prior to WC2.5, what has changed?

Nothing in the cache classes etc.

Maybe instead of fixating on sessions you should ensure cart is excluded from minification and page caching again. Definitely looks like its caching HTML rather than database stuff. Also, post your system status report so everyone can see what you’re running. Finally, do a test with a different theme and see if still affected.

Update: in the midst of searching for a solution my server had major connectivity issues. Seems to be back online and while offline, I did some digging. Even though i hade w3tc exclude cart from page cache, it was still browser caching with a max-age of 3600. i turned expires header off for html only and chose “cache with validation” rather than “cache with max-age”. so far this seems to be working but will test further. Thanks Mike for your help, it should be made known to add “woocommerce_sessions” to query stem to ignore if DB caching is used in W3TC.
