Summary: HTTP Post Request is set to recoverable on timeout
waiting for response from tomcat
Product: Tomcat Connectors
Version: 1.2.28
Platform: PC
OS/Version: Linux
Status: NEW
Severity: major
Priority: P2
Component: mod_jk
AssignedTo: dev@tomcat.apache.org
ReportedBy: discoversud...@gmail.com
mod_jk retries http post requests in case of timeout in getting response from
tomcat with default configurations(no retries or recovery_options specified).
AFAIK HTTP Get and Head requests are only considered idempotent, shouldn't post
requests be non-recoverable ?
We are using apache <--> mod_jk-1.2.28 <--AJP13--> tomcat
We also are using DisableReuse flag in mod_jk config
I understand this can be fixed with disabling the recovery option.
Wondering if its a default config issue or a bug in mod_jk.
If it is intentional can someone please explain the intention ?
