Description

When you allow a Magento Route through the Venia proxy there is no possible way to determine the current store. By enabling the xfwd option in the proxyMiddleware it is possible to allow Magento to determine the current store based on HTTPX_FORWARDEDHOST.

For example when you have a Magento Module which generates a PDF file with product data it should also have the store information to display the correct language and storeview values of the product.

  'HTTP*X_FORWARDED*FOR' => '127.0.0.1',
  'HTTP*X_FORWARDED*PORT' => '8227',
  'HTTP*X_FORWARDED*PROTO' => 'https',
  'HTTP*X_FORWARDED*HOST' => 'pwa-studio-xelbq.local.pwadev:8227',

Checklist

[!--- Go over all the following points, and make sure you've done anything necessary -->

• I have added tests to cover my changes, if necessary.
• I have added translations for new strings, if necessary.
• I have updated the documentation accordingly, if necessary.

Test Plan: (provided by contributor)

• create 2 storeviews (one enUS and enUK)
• open a controller by adding a venia Proxy (for example /contacts )
• change the layout for enUS to set the Page Title including en_US and for en_US include enUK in the name
• you will always see the default store because there is no proxy reference given
• pwastudio.com/contacts > should return Contacts - en_US
• pwastudio.co.uk/contacts > should return Contacts - en_UK
• switch based on proxy reference data can be added by this change and be used to determine the actual country
