<p>I want to send http requests from a fixed, outgoing port. How can I do this in Go?</p>

Use that client to make HTTP requests.</p></pre>me_again: <pre><p>I’m curious why you want to do that? </p></pre>drink_with_me_to_day: <pre><p>Making a network test where I need to manage outgoing data QOS. Having fixed ports would make the SDN flows easy to configure.</p></pre>xandout: <pre><p>For the most part you don't set the outbound port for any communication. Your OS picks a random, unused high number port and you use that. </p>
<p>If you can tell us the underlying OS it may be possible to find a solution. </p></pre>
