-------------------------------
Summary: parent proxy crashes with TSHttpTxnParentProxySet
Key: TS-4388
URL: https://issues.apache.org/jira/browse/TS-4388
Project: Traffic Server
Issue Type: Bug
Components: Plugins
Reporter: James Peach
If you call {{TSHttpTxnParentProxySet}} to explicitly set a parent proxy
target, the proxy request will fail because it is not initialized correctly.
