Unable to set custom price when the cache is enabled

[arijit-de93]

I am using Magento 2.1.Cache is enabled in my magento.

I am using catalog_product_collection_load_after event for loading all the products when a category is triggered from the front-end and to set a custom price for the products.

And similarly, catalog_product_collection_load_after event I have used to set a custom price when a particular product will be viewed.

The problem that I am facing is described below:-
1)The above mentioned two events is getting triggered sometimes not all the time.
2)And if it is triggered, I am failing to get the customer id from the session and at the same time not able to set the price.I am using setPrice($customPrice) method for setting.

These above issues does not arise when the cache is disabled.

I will very thankful if you can provide your ideas or a way around about how I can set a custom price for a product when the cache is enabled.

What cache backend are you using? Varnish PLUS REDIS (SESSION/BACKEND) are the only functioning cache backends - built in file/zend based caching is broken!

@southerncomputer
I am not using any custom caching process. I am using the same Cache process of Magento 2.0.

Thanks

I'd suggest implementing Varnish as a cache, it should reduce the problem points. It is known issue that the built in cache process for Magento 2 is not for production quality and causes pain-points!

See ticket #3572 if you don't believe me!
