PostMethod very slow 'out of the box' for /j_security_check
-----------------------------------------------------------
Key: HTTPCLIENT-1048
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1048
Project: HttpComponents HttpClient
Issue Type: Bug
Affects Versions: 4.0.3
Environment: Java 6, Tomcat 6, JBoss 5.1
Reporter: Kennard Consulting
HttpClient's default settings include adding an...
Expect: 100-continue
...header to every PostMethod. This seems to interact poorly with Tomcat's (and
possibly other Java EE containers) FormAuthenticator. I tested on both Tomcat 6
and JBoss 5.1.0 (which I believe uses a fork of Tomcat). Testing both
with/without the 'Expect' header I see '/j_security_check' login times of:
With Expect header: 2012ms
Without Expect header: 8ms
So the default is some 250x slower. This can make a dramatic difference if you
are using HttpClient to simulate logging in and retrieving information.
I include a test WAR. To deploy it:
1. Copy into /webapps
2. Edit conf/tomcat-users.xml to enable the tomcat/tomcat username/password
3. Run Tomcat
4. Hit http://localhost:8080/ExpectTest
5. Log in as tomcat/tomcat
6. Hit 'Start Test'

Richard
