JMeter: How to supply a hostname which contains a forward slash in JMeter user defined variables?

Question

The hostname being supplied to the JMeter test plan, contains a forward slash and has been defined in the User defined variables section. However, each time the test is run, the following is seen in the response message:

Response message:Non HTTP response message: Illegal character found in host: '/'

The hostname provided: Jmetertest.com/test

Is there any way around this? Thanks in advance! :)

Answer 1

A DNS hostname cannot contain slash.

The Internet standards (Request for Comments) for protocols specify that labels may contain only the ASCII letters a through z (in a case-insensitive manner), the digits 0 through 9, and the hyphen-minus character ('-'). The original specification of hostnames required that labels start with an alpha character, and not end with a hyphen

So you need to split hostname from the URL Path

i.e. in the following URL:

https://example.com/foo?bar=baz

• https - the protocol
• example.com - is the hostname
• /foo is the path
• ?bar=baz is the query string

In the HTTP Request sampler you can only have the following syntax:

If you put anything than allowed characters into "Server name of IP" field you will get an error.

Theoretically it's possible to put the full URL into the "Path" field like:

But in this case configuration elements like HTTP Cookie Manager may stop working.
