Note: This exclusion only needs to be done on your parent site (the server where you have ProjectHuddle installed). You don’t need to add these cache exclusions on your child sites!
If you host your site on Flywheel, you may encounter some issues with access links not working when visiting the website project. This is due to aggressive page caching (which is a good thing!), but it can be easily resolved by requesting that Flywheel set up a special cache exception.
To do this, simply submit a support ticket to Flywheel via their support portal and ask them to exclude our session cookie from the cache.
To make things really easy for you, feel free to copy and paste this sample ticket:
My site runs the ProjectHuddle feedback plugin and we need to bypass varnish caching for their cookie. The ProjectHuddle team has instructed us to ask you to place a cache exception for their cookie.
Could you please bypass varnish caching for the _wp_session cookie?
