title: Http redirect for content on relative paths
body: <p>Essentially what my use case is, a 3rd party server only support POST on a specific integration url. but I want a browser to hit it from a normal html link (I have no control over either systems code, I can only configure the destination url for the link)</p>
  <p>To solve or this I have written a web hosted app (done in Mirth Connect - but the server tech in theory shouldn't matter). The objective of my app is to cat the GET and convert it to a POST</p>
  <p>My systems logic:
  My web server receives an HTTP GET from a browser, grabs the query strings.
  The server then performs an HTTP POST on a 3rd party server, and grabs the html result
  The server then returns the original html and delivers it as the result to the original http request from the browser</p>
  <p>This works great, the issue comes in with content hosted on the 3rd party server that is referenced with a relative path (css, js, images, etc).</p>
  <p>Because I have &quot;tricked&quot; the browser into thinking it received the html from my system, it looks on my server for the content (which will all 404).</p>
  <p>Without having to handle the fetching of all the content myself, is there a way to tell a browser to redirect all further queries to the 3rd party server?</p>
  <p>I tried making my HTTP GET return a status 301 or 302 with the location being the base address of the 3rd party server, but this obviously tells the browser to redirect completely</p>
