comment How did OpenLayers 3 managed to export map from other domain?
I think this is incorrect. If you view the application's network traffic you will see the tiles being sourced from a different domain by the browser. No proxy is being used.

comment Is it possible to generate a heatmap on the server-side using ArcGIS Server?
generating XML can be extremely fast so the additional time required to generate the SLD really just depends on how long the database query takes to retrieve the data that the SLD is based on.

comment Is it possible to generate a heatmap on the server-side using ArcGIS Server?
the SLD is a stylesheet that tells the map server which colour / size (if points) / border thicknes etc. to use when drawing features. You make one WMS request to the map server and that request includes some information about the SLD you want to use. The map server retrieves that SLD under the covers - which is generated dynamically to say either a) feature 1 is green, feature 2 is red etc. or b) population 0 to <= 1,000 is blue, population 1001 to <= 2000 is pink etc. - and then the map server renders and returns the image using those colours

comment What's the correct link for adding GeoServer WFS to ArcMap?
I think when I did this I had to specify the layer in the URL and could only add one at a time

comment CQL filter causing slowness in Java \ Geoserver app
I'm pretty sure filtering by ID should not cause such a slow-down if your ID field is indexed, even with thousands of IDs. Are you sure the problem is not in rendering the features themselves? Also beware very long queries. Eventually your DBMS will refuse to process the query that GeoServer gives it (1 MB default max in MySQL)

comment ArcGIS Desktop can't return concurrent license
restarting the license server can sometimes help with these disagreements. After having a similar problem I made sure to always reduce the license borrowing time limit to 1 day so that things would always fix themselves soon enough

comment WMSGetFeatureInfo Not Returning Results
I think you should use Fiddler and compare the raw request content for the OpenLayers request and your paste-into-browser request. You may find that your request headers are slightly different, or comparing the responses (if you even get one) might provide some clues. Also you mention that event.text is not as expected but you don't say whether the event object itself has anything else from the server

comment Could not load file or assembly : ESRI.ArcGIS.ADF.Local.dll
You could first try going to the project's references and removing all ArcGIS DLLs (make a list / screenshot before you do this). Then use the VS dialog to add references and get them all from the new machine's GAC (assuming they are in there)

comment Could not load file or assembly : ESRI.ArcGIS.ADF.Local.dll
Questions: 1) have you installed the WebADF 10.0 on the new machine? 2) Are both machines 64-bit? 3) Are you also upgrading from one version of the WebADF to another as part of this change?

comment Why GetFeatureInfo does not work?
this can be confusing at first as your map images are presumably showing up just fine, and this is because images are not affected by the same-origin policy

What's the domain of your site in the browser's address bar? This could be the issue: en.wikipedia.org/wiki/Same-origin_policy

comment OpenLayers is not defined while accessing over the html and js
you need to provide your HTML and also explain how you're accessing your site, e.g. localhost... or localhost/some/site/name...

comment OpenLayers LineString: Not displaying the line (array of points)
the only definite difference I see is that your question's example is missing new OpenLayers.Feature.Vector. Also, I'm not sure how the Point object's toString function works in alert(path_travelled) but it seems like the two examples are plotting in different parts of the world (in your question the positive ordinate is first, in your codeshare it's second). Are you sure it's not just appearing somewhere you don't expect?

what is the coordinate system of your map? You might find your line somewhere near 0,0

comment how to make web mapping project run (serve map) faster
ideally you'd just ask whoever configured your GeoServer installation. Next best option might be exploring the GeoWebCache interface from the GeoServer administration page. If that's no use you might end up trawling the file system looking for your tiles. I think you should give some indication of what kind of performance you're getting, i.e. if tiles render after 2 - 3 seconds or it takes longer. Also read docs.geoserver.org/2.1.3/user/production/java.html on JAI and performance (though don't expect a massive change)
