NIFI-1711 Client-side JS for proxy-friendly URLs. This closes #316
> Content Viewer Format Links Do Not Use Proxy Settings
> -----------------------------------------------------
>
> Key: NIFI-1711
> URL: https://issues.apache.org/jira/browse/NIFI-1711
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core UI
> Affects Versions: 0.6.0
> Reporter: James Wing
> Priority: Minor
> Attachments: nifi-content-viewer-format-options.png
>
>
> The content viewer format options do not use proxy settings, and generate bad
> links on a NiFi installation behind a proxy. Proxy settings were provided
> via the HTTP headers X-ProxyScheme, X-ProxyHost, and X-ProxyPort. The
> content viewer will initially display unformatted content fine, but then
> selecting different options such as 'formatted' results in a 404.
> !nifi-content-viewer-format-options.png!
> The URL seems to start life in
> [header.jsp|https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-web/nifi-web-content-viewer/src/main/webapp/WEB-INF/jsp/header.jsp]:
> {code}
> <span id="requestUrl" class="hidden"><%=
> org.apache.nifi.util.EscapeUtils.escapeHtml(request.getRequestURL().toString())
> %></span>
> {code}
> Which was sent to the client as follows:
> {code}
> <span id="requestUrl" class="hidden">https://nifi/nifi-content-viewer/</span>
> {code}
> On selecting 'formatted',the event handling Javascript concatenates this with
> the new view options to navigate to URLs like this:
> {code}
> https://nifi/nifi-content-viewer/?mode=Formatted&access_token=MjZvmd5...
> {code}
> I believe properly generating links that respect the proxy settings on the
> server would require logic similar to that of
> [ApplicationResource.generateResourceUri()|https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-web/nifi-web-api/src/main/java/org/apache/nifi/web/api/ApplicationResource.java#L97].
> It might also be possible to simply format the links on the client.
