comment Create base maps from vector data
In GeoServer you will create a 'group layer' which combines your separate 5 layers, then the user will request this. This will also be used to generate your tile cache

comment How did OpenLayers 3 managed to export map from other domain?
you're still describing something that is irrelevant in this question. The site referenced in the question does not use a proxy.cgi script. If you don't believe me please see: i.imgur.com/gFMrczn.png If a proxy was used the tiles would come from something like ol3js.org/proxy.cgi, but they don't - they come from an entirely separate domain. The question's poster sees this and understands this means the canvas is indeed tainted. Your answer and comments are relevant to different questions but not this one. One may therefore choose to describe the answer as 'incorrect'

comment How did OpenLayers 3 managed to export map from other domain?
I mean in this case you are incorrect. I'm well aware that the proxy approach works, but the referenced application doesn't use it.

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?
