As mentioned by Fran in this Topic : https://www.princexml.com/forum/topic/668/java-http-proxy

Is it possible to define a list to exclude some domains to by pass the http-proxy?

Regards,
Andreas

We don't have an option for this yet, we will investigate.

The easiest solution might be to setup a proxy for the proxy.

Thx for your replies.

We shared the shame idea, but yesterday I found another solution.

Because princexml uses curl, I can use the curl supported environment variables http_proxy and no_proxy.

By removing the proxy parameter from the command

prince --http-proxy=export-proxy:3128

And define the proxy rules in the environment variables that curls supports, I was able to exclude specific and wildcard domains from the proxy.

Example:

 https_proxy=export-proxy:3128 http_proxy=export-proxy:3128 no_proxy=www.wikipedia.org,.lorempixel.com "/usr/bin/prince"

more information can be found here: https://curl.haxx.se/libcurl/c/CURLOPT_NOPROXY.html

I tested this on Debian 10

Hopefully its is useful for others.

That's excellent! Thanks for sharing.

Excellent, Andreas! Do you mind if we mention this approach in our documentation?

That would be perfect!,
so.. no I dont mind
