Hi All,  I've got an odd issue that I can easily reproduce in a specific environment.  It's slightly complicated to explain ... Short version: JavaScript API requests to a map service (legend, query and export) fail after the first successful attempt.  The response is a 504.  Using fiddler to trace these request, I've narrowed it down to the IF-NONE-MATCH header in the request.  Using fiddler, I reproduce the failures, then remove this header value and the requests will process successfully.  It appears to me that some interaction between the proxy, firewalls, arcgis server, etc are having a mis-communication for these request that would probably result in a 304 type response.   I don't control the network, firewall environment so I might be missing some details but this is my view of the setup: INTERNET          |         V PUBLIC FIREWALL          |         V LOAD BALANCER           |         V DMZ WEB SERVER (x2 i think)    * web app/site + proxy    * arcgis web adapter site           |         V INTERNAL FIREWALL           |         V ARCGIS SERVER (v10.5)    * secure map service Here's the sequence of events I've traced so far and can reliably and consistently reproduce: 1. Start with a cleared browser cache or in-private browser window 2. Load web app/site in browser..    * all the web site resources (html, css, js etc) load correctly    * AGS REST API requests kick off and are successful:       * https://{mywebserver/site}/proxy.ashx?https://{myarcgiswebadpater/service}/MapServer/3/query?f=json...       * https://{mywebserver/site}/proxy.ashx?https://{myarcgiswebadpater/service}/MapServer/export?f=image...       * https://{mywebserver/site}/proxy.ashx?https://{myarcgiswebadpater/service}/MapServer/legend?f=json...    NOTE: none of these requests have an IF-NONE-MATCH header in the request and all have a ETAG header with a specific value in the response 3. Refresh the web app using the default browser button    * all the web site resources (html, css, js etc) load correctly    * AGS REST API requests kick off and all FAIL - status 504     NOTE: in each request there is now a IF-NONE-MATCH header in the request with a value that corresponds to the ETAG from the equivalent request in step #2.  When I trap these requests in Fiddler and remove the IF-NONE-MATCH header, they'll execute successfully.   A few more details:  * Step #3 will continue to fail until a full browser cache clear or new in-private window...obvisouly since the caching is reset.  It does appear to reset after some minutes interval but I haven't narrowed down the time window.   * When I run the website from my local dev machine or test server (web app and proxy) directed to the live map service, the refreshes will correctly load, the request headers are identical and the responses have 304 status codes.  This seems like normal browser/internet caching stuff and it works correctly from an outside web server so I'm guessing something in the hosting environment isn't configured correctly to rematch these caching requests?  Anyone have suggestions on what settings or tweaks I can pass along to the network ops staff that might remedy the current situation?  Thanks!!!  ...

See my discussion here: https://community.esri.com/thread/215959-how-do-we-smooth-out-the-self-hosted-wab-app-and-the-oauth-approve-workflow for details... but essentially when you self-host WAB apps that connect to secure portal webmaps, the user is forced to jump thru a lot of login dialogs.  This can be simplified by changing the portal mode from "pop-up" to "in-page" but that setting is hard-coded in the tokenUtils file.  A simple extra true/false setting in the config could allow for this to be changed.  ...

Hi All,  I have a server environment where we publish services via the 'create service definition - no server connection" in ArcMap, hand the .SD file off to an admin that then publishes the service via the web manager.   There's the option to 'overwrite a service' from ArcMap but it seems like this is only avialable for the connected workflow.  Is this process just a wizard that does the following steps in automation: 1. Create service definition 2. Import from existing service 3. Delete existing 4. Publish new So our workflow to "overwrite" in this disconnected environment is those 4 manual steps or is there a shortcut?  Thanks Fred ... View more

We have number of self hosted JavaScript applications with custom widgets and functionality (these have to be self hosted correct?).   The users are getting pretty annoyed with the extra clicks when opening these apps.  Right now they generally access the apps from links on the portal banner so they are already signed into the online portal.  When the browser tab opens, the application frame is loaded, then they are presented with a simple "Please sign in to continue" dialog which then takes them to a pop-up web page with the "ThisApp wants to access your ArcGIS Online account information" Approve dialog.   * How do we make this a simpler user experience?  * Can we add code to get thru these dialogs with at least one click rather than two? * Why can't it "remember" that the user has Approved the app access?  * Do we need run a local portal to make this workflow smooth?  * We like using the online portal to create and store the "web maps" but that little bit of niceness for the admins is less a priority over the actual user experience so maybe we should drop using online web map for self hosted apps?  I'm open to anything that make this smoother for the user i.e. they should only have to login once per session and approve once per application. We can add code, proxies, wrappers etc...  thanks  Fred ... View more
