Depends on what you meant by &quot;Payload&quot; in the first comment. I assumed it to mean &quot;a bunch of bytes&quot;, so you could have just used URL parameters, which don&#x27;t have a standardised maximum length, but you can generally rely up to about 2,000[0] or so. If that wasn&#x27;t enough, you could split up the requests like the other comments said[1], or go full hack-mode and use the cookies[2]. (using a Set-Cookie response header to clear them after the request was made)<p>Edit: Of course this isn&#x27;t recommended, but I think the time wasted trying to convince the (seemingly terrible) manager could have been better spent.<p>[0] <a href="http:&#x2F;&#x2F;www.boutell.com&#x2F;newfaq&#x2F;misc&#x2F;urllength.html" rel="nofollow">http:&#x2F;&#x2F;www.boutell.com&#x2F;newfaq&#x2F;misc&#x2F;urllength.html</a><p>[1] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10649995" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10649995</a><p>[2] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10650110" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=10650110</a>
