I would like to pass an array through a http header.

Would it be acceptable to name multiple params the same name, and that way I would know that they belong to an array just like in a get request query string? Example:

CurrentHeaderArray: myarray[]=value1&myarray[]=value2&myarray[]=value3

There is already a stackoverflow answer to pass it through the query string of a get request, see this hyper link. How to pass an array within a query string?

Just url encode the parameters and pass them under one parameter like this: &myArray=%26myArray%3DfirstItem%26myArray%3DSecondItem where %26 is url encoded for & and %3D is url encoded for =
