When running CA Access Gateway (SPS) as an SSO front end to a web application.
In the server.log for CA Access Gateway (SPS), the following message on certain page requests is seen:
[ERROR] - org.apache.http.ConnectionClosedException: Premature end of chunk coded message body: closing chunk expected
[01/Feb/2021:19:55:23-110] [ERROR] - at org.apache.http.impl.io.ChunkedInputStream.getChunkSize(ChunkedInputStream.java:266)
The associated log message in the httpd log file is:
10.0.0.1 - - [01/Feb/2021:19:55:23 +0000] "GET /myApp/myPage/ HTTP/1.1" 200 -
This does not appear to impact the end users who access the application behind CA Access Gateway (SPS). How this message can be eliminated?
Release : ALL
Component : ACCESS GATEWAY
The back-end server is not sending the expected zero-length closing chunk resulting in this error.
CA Access Gateway (SPS) will still process these requests, but ultimately the back-end host should be corrected to send the expected chunk and thus be in compliance with HTTP standards.
