>             Project: HttpComponents HttpClient
>          Issue Type: Bug
>    Affects Versions: 4.0.3
>         Environment: Java 6, Tomcat 6, JBoss 5.1

> 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'
> Regards,
