var ErrMalformedProxyURL = errors.New("malformed URL value found in INSTANA_ENDPOINT_PROXY, ignoring")

ErrMalformedProxyURL is returned by NewHTTPClient() when the INSTANA_ENDPOINT_PROXY= env var contains a malformed URL string

Functions

func NewHTTPClient added in v1.20.0 

func NewHTTPClient(timeout time.Duration) (*http.Client, error)

NewHTTPClient returns an http.Client configured for sending requests to the Instana serverless acceptor. If INSTANA_ENDPOINT_PROXY= env var is populated with a vaild URL, the returned client will use it as an HTTP proxy. If the value is malformed, this setting is ignored and ErrMalformedProxyURL error is returned. The returned http.Client instance in this case is usable, but does not use a proxy to connect to the acceptor.

Types
