How to override Host header
How can I override Host header in HTTP request?
I tried adding HTTP Header Manager and set Host header in it, but I see no
changes in my HTTP requests.
Adding to "hosts" file is not applicable since I have no root privileges at
test generator.
Any ideas?
Best regards,
Andrey

Thanks.
In which case, the OP may wish to use Bugzilla to create an
enhancement request to allow the Header Manager to provide the Host
name.
This might also affect Proxy recording.

Thank you, appreciate fixing it.

On further reflection, JMeter should be able to set whatever headers
it wants, so the next release of JMeter will include this by default.

Thanks.
As noted there, you can edit the system.properties file to define the property.
Perhaps that should be done by default for the next release of JMeter?
Or should it be up to users to define the value?
In any case, it would make sense to at least add a comment in the file
about the setting.

Re: How to override Host header

I needed to override Host header and debugged a little to find that this
header is being considered as one of the "restricted" headers and so is
being silently dropped. The workaround is to set
"sun.net.http.allowRestrictedHeaders" to "true". I was able to verify that
this works by passing in -Dsun.net.http.allowRestrictedHeaders=true
argument on the command-line. When I tried to set the same property in the
context of a User Defined Variable using __setProperty() function, I could
see that the property value has changed, but the Host header was still
dropped, suggesting that the property value needs to be changed sooner than
that. I am not sure if there is another context that can make it possible to
programmatically change this value.
I went ahead and opened this enhancement request:

[As already stated:]
Not currently possible. You would need to change the JMeter code.
Feel free to raise a Bugzilla enhancement request.

How this can be done? I put a "HTTP Header Manager" (with a "Host" header
specified in it) into a "HTTP Request HTTPClient" sampler (where "Server
Name" is provided as an IP address and "Port Number" is also specified as it
is non-standart). After that (as tcpdump on the target server says) the
"Host" header in the request from JMeter still contains "IP:port" but not
the domain name provided in the "HTTP Header Manager".
I use JMeter 2.4 r961953 with JRE 1.6.0_24 on Windows 7 Starter SP1.

HTTP Client does allow you to override the host header and specify a virtual
host (e.g. when implementing a reverse proxy this is useful)

The Host header is generated by the HTTP stack from the URL, and
cannot currently be overridden.

If the target host is a virtual host, at some point the virtual host
names will need to be defined in DNS, otherwise it will not be
accessible by browsers. So maybe you can bring that stage forward.
I don't know whether the Http implementations allow the host to be
specified; your only other option at present is to change the JMeter
code locally to remove the host restriction.
