Unity, UnityWebRequest and Proxies

It seems like nobody really solved the problems described in this thread:
https://forum.unity.com/threads/make-web-requests-with-a-proxy.550813/
And crol got ignored.

How can you override or set the proxy when using UnityWebRequest?
If we can't, why?

How can you set the proxy credentials when using UnityWebRequest?
Setting "Proxy-Authentication" header does not work, you will get:
InvalidOperationException: Cannot override system-specified headers

How can you set the proxy credentials for Unity services?
User reporting and analytics do not work behind a proxy because we can't set the credentials.

Thanks for any help

 

Currently we are testing this on Windows 10 Standalone. But iOS and Android are a prioritity as well.

Our apps are mostly used in a business environment, inside a corporate network often with proxy.
These proxies often require some kind of authentication.
Some clients might add whitelists for our apps some don't.

The problem isn't that proxies aren't used, but that we can not set the credentials.
Services like user reporting, unitywebrequest etc. break if authentication is required.
For this situations we added a form where the user can enter his or her proxy credentials.
This works for our own requests to our backend, but we can't forward this information to unity.
This seems to be normal behaviour as you can see in other apps like

• Chrome or other browsers: Credential popup if needed
• Adobe Creative Cloud: Asks for proxy credentials if needed

Default Credentials do not work in every situation.


If this is not considered best-practice, what is?
How are we supposed to get our apps to work in a network environment where users have to
specify proxy credentials?

 

@NeonOby Was there ever a follow up to this?

Hi @NeonOby and @Aurimas-Cernius is there any update on this thread?

I've the same problem that @NeonOby with Unity 2019.4.20f1

 

I believe the request was to submit a bug. Then post the BugID here.

 

Hi,

The only way I could find so far is to use the c# WebClient for downloading files or
HttpWebRequest for getting raw data.

With these two class, you can set the proxy credentials and address, using their .Proxy Fields using the
WebProxy class.

This is not the case for major corporates and their IT strategies, we made several requests to explain how their proxies was setup, and took pleasure in never telling us, probably for security reasons...

I am surprised that we all the new clients in automotive you have, you did not get any feedback for this. if you ask some of your fields engineers to check on that when thy have a chance, you will get to the same conclusion. Or Maybe these clients make applications that never really needs/can't access online data ( rules made up by the same security guys who setup the proxies and responsible for security).

So UnityHttpRequest should provide proxy support inside its class.
