Thanks for the reply Derek.
However I'm not sure that answers the question. I am using a proxy for large queries, but after the query geometry JSON string length exceeds about 4400 characters in length, the selectFeatures method fails to select any features.
Even with a proxy page, (downloaded from the ESRI link), this problem occurs. Just curious what the limit for large query length might be. Or should I not be seeing this strange arbitrary limit on my end? This is using IE8, btw.
Thanks,
Andrew
