An Adobe Commerce developer is tasked with adding a new block on every page of the site. The contents of this block are supposed to vary depending on the gender of the customer when the customer is logged in. This is a restricted site, only logged in users can access it. The developer has just finished developing the block which is now able to display different contents depending on the current customer available in MagentoCustomerModelSession.
Having performance in mind, the developer wants to be able to keep using Varnish, in an optimized way, while allowing the contents of the block to change according to the gender of the customer.
What would the developer do to achieve this?
- A . Create a before plugin on MagentoFrameworkAppHttpContext::getVaryString, use the setValue()method on the subject with a chosen key and the value of the gender of the current customer, and add the block to the default handle.
- B . Create a new controller extending MagentoFrameworkAppActionAction with a layout handle containing the block with a cacheable="false" property. Add another block to the default handle in charge of making a systematic ajax call to the newly created controller and render the output.

- D . Directly modify the customer_session model to include gender-specific logic.

"description": "New JSmith design",
"extension_attributes": {
"logo size": "small"
},
"custom_attributes": {
"artist": "James Smith"
}
}
