Service Callout headers

[Denis_KALITVI]

Hi,

We found a bug, we think in the Service Callout policy:

1. Create proxy

2. Put Service callout to call external API

2.1 use <Copy> <Headers>true flag inside Callout

3. Transfer from client side any header with values splitter by commas: header-name: a,b

As a result, Service Callout will send to this API duplicate headers:

header-name: a

header-name: b

In some cases, backend will die because of this - some backends know to aggregate the headers in to one, with multiple values, some - not.

We opened ticket for that, but I wanted to ask community what in their opinion are the best and most efficient workaround on this.

This we have experienced earlier in some reqyears.

We used request.header.name.values.string to get all in one header
