    Proj4js will create the URL and load it for you automatically (for
    EPSG codes anyway).&nbsp; The only thing you need to do is wait for it to
    be loaded by checking the readyToUse flag on the projection object.<br>

      <div>I've noticed that you can use the <a moz-do-not-send="true"
          href="http://spatialreference.org">spatialreference.org</a>
        REST interface to make calls like:</div>

          href="http://spatialreference.org/ref/epsg/2805/proj4js/">http://spatialreference.org/ref/epsg/2805/proj4js/</a></div>
      <div><br>
      </div>
      <div>which gives you the javascript code needed to use the
        projection.</div>
      <div><br>
      </div>
      <div>I assume I need to generate a URL for my given projection,
        get the contents of the URL and run it as JavaScript.
        &nbsp;Unfortunately I've got no idea how to do this!</div>

                      Hi,
                      <div><br>
                      </div>
                      <div>I'm trying to use proj4js in my project and
                        will need to project to various CRSs. &nbsp;The
                        projection codes are submitted by the user, so I
                        have no way of knowing what CRSs will be used.
                        &nbsp;I've looked at the user guide and it says that
                        proj4js can dynamically look up CRS info at
                        run-time, but I can't figure out how to set this
                        up. &nbsp;When I try and carry out a projection, I
                        just get the original values back...</div>
                      <div><br>
                      </div>
                      <div>Any help would be appreciated,</div>
