[jira] [Updated] (TS-2298) 400 Multi-Hop Cycle detected with
.insert_request_via_str
[ https://issues.apache.org/jira/browse/TS-2298?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jan-Frode Myklebust updated TS-2298:
------------------------------------
Description:
We're seeing "400 Multi-Hop Cycle detected" problems when proxy.config.http.insert_request_via_str is enabled. We see the same problem on both v4.0.2, v3.2.3 and v3.2.5.
The configuration we have that triggers this is:
{noformat}
map http://www.example.com/ http://web1.example.net/
map https://api.example.com http://api1.examle.net/
{noformat}
where web1.example.net is using mod_proxy to proxy some requests to https://api.services.example.com:
{noformat}
SSLProxyEngine On
ProxyPass /api/menu https://api.example.com/test/api/menu
{noformat}
If www.example.com and api.example.com is going trough the same trafficserver with proxy.config.http.insert_request_via_str enabled we get the Multi-Hop Cycle detected error. If they are going trough different physical hosts, or if we disable proxy.config.http.insert_request_via_str then the problem goes away.
