Sent request with no User-Agent header

[Antony Bowesman]

Using JMeter 3.3

How can I send an http request without a User-Agent header.

I have a HeaderManager for the request, but if I don't specify as UA header, it sends something like

User-Agent: Apache-HttpClient/4.5.3 (Java/1.8.0_102)

whereas if I specify User-Agent as an empty value, it will send an empty UA header.

It seems like HttpProtocolParams will add the http.useragent default property, so will effectively mandate the UA header.

As per HttpClient JavaDoc
<http://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/client/DefaultHttpClient.html>

This class sets up the following parameters

*

if not explicitly set

*

Version: HttpVersion.HTTP_1_1
ContentCharset: HTTP.DEFAULT_CONTENT_CHARSET
NoTcpDelay: true
SocketBufferSize: 8192

*

UserAgent: Apache-HttpClient/release (java 1.5)

*

I don't think there is an easy way of disabling this (unless you would like
to go for Reflection
<https://www.oracle.com/technetwork/articles/java/javareflection-1536171.html>
)

If you don't want the User-Agent header you can switch to "Java"
implementation, the setting lives under "Advanced" tab of the HTTP Request
sampler (or even better HTTP Request Defaults
<https://www.blazemeter.com/blog/why-its-so-important-use-jmeters-http-request-defaults>
, this way the setting will be applied to all the HTTP Request samplers in
its scope and you will not have to revisit each one individually)

Also be aware that according to JMeter Best Practices you should always be
using the latest version of JMeter
<https://jmeter.apache.org/usermanual/best-practices.html#use_latest_version>
so consider upgrading to JMeter 5.0 (or whatever is available at JMeter
Downloads <https://jmeter.apache.org/download_jmeter.cgi> page) on next
available opportunity
