How to change HTTP protocol version to HTTP 1.0

I have unsuccessfully searched through the Postman community and online in general.
How do you change the HTTP protocol from HTTP 1.1 to HTTP 1.0?
In Fiddler there is a drop down box that lets you choose from several versions.
I cannot seem to figure out how to do that in Postman.


I have the same issue. I thought there would be a response by now. Thanks for the tip on Fiddler.

Hi @clanholm and @zimbrich,

You can’t choose any protocol other than http/1.1 at this time. One option for getting requests into http/1.0 is to run a local proxy and point it to your target server.

Some options:

  • Using proxy_http_version, you can configure NGINX to forward traffic as http/1.0.
  • Using mod_proxy, you can run an http/1.1-to-http/1.0 proxy in Apache HTTP Server.
