When using a proxy, an additional HTTP response code may appear at the start of the header.
For example, when using https over a proxy there may be 'HTTP/1.0 200 Connection Established'. Other codes are also possible and some may come with their own headers.
If using the return value containing all headers, this function can be called to remove unwanted doubles.
Note that it is not possible to distinguish this situation from valid data unless you know the actual response part (below the headers) will not be included in this string, or else will not 'look like' HTTP headers. As a result it is not safe to call this function for general data.
string | $input | Input HTTP response |
string | HTTP response with additional headers stripped if any |
