lost request chunk when using mod_proxy_ajp

[michael_jank]

Hi,

I am using Wildfly CR1 together with an Apache, communicating via mod_proxy_ajp.

When sending form posts containing so many parameters that the request is chunked, sometimes it happens that the last chunk is lost somewhere between Apache and the web application. I can trace that the Apache writes all parameters into AJP, but not all make it into the web application, having the idea that something happens on request parsing in undertow.

This effect does not happen on all requests, however, it is reproducable regularly.

When using mod_proxy_http between Apache and Wildfly, everything seems fine.

Are there any known issues concerning chunked requests when using mod_proxy_ajp?

Thanks and cheers,

Michael

Hi Michael,

I not aware of any neither I see any open issues for AJP at the moment (filter: Issue Navigator - JBoss Issue Tracker).

1. Can you try with latest WildFly build from master? WildFly nightly builds available
2. Unlikely this would show something, but you might try with mod_cluster and AJP listener to see if you can get the same issue. mod_cluster - JBoss Community
