	JMeter 2.5.1 snap: http://tinypic.com/r/qn045e/5

I'm using HTTPS.

The POST takes longer, the GET does not. (In the images, the "Homepage" is a
GET, the "Login" is a POST.)

Do I have to build JMeter to get the fixed HTTP client, or is there
somewhere that I can get it already ready to go (for Windows XP, 32bit, Java
JRE1.6.0_29)?

I consider myself a medium to advanced "user" of JMeter, but I'm not really
a developer (of any kind, anymore)...

No, it cannot.

Use a public hosting service and include the URL in the e-mail.

Do you use HTTP or HTTPS?

Do both GET and POST show elapsed time increases?

There have been some fixes to HC4 since 2.5.1.
