Query Task Not returning Results when Query is having More data

There is a customized functionality created in Geocortex which searches the Boundary using the DMA and other layers. The functionality was working fine but as we have created a join on the DMA layer, functionality got broken. We have investigated it further and it seems the Query task is not able to run for queries having more data while for queries which is having less data the functionality is returning the result successfully.

We have tried running the Query in ArcGIS Server for the layer and it didn't work for GET while when we Click on POST it returns the results for the query. It seems the Query is not able to work properly when data is large and GET command is used.

Can someone please suggest on this? It seems we have break query in two parts to make it work?

GET may stop working if the 'where' clause is so long that the URL exceeds its maximum length. Could you give an example of what your query looks like?

(The amount of data returned by ArcGIS shouldn't matter, unless you receive a timeout)

HI Berend,

Thanks for your valuable input.

The issue is now resolved as I was getting the 500 error and on ArcGIS Server I have updated the timeout for the map service and it worked fine.
