Is there a limit to the length of the JSON string when sending a POST request to the REST interface aof ArcGIS for Server's Printing Tools' "Export Web Map Task" ?
I didn't find any documentation to any limitations so I presume only firewall limitations apply. But I need to make sure there are no such limits on ArcGIS for Server before starting to implement my application.
The reason I ask is that  I ran into a similar problem when using a FeatureService. In that case the JSON string got cut off by the REST interface after about 2000 features. The solution to this was rather simple: splitting the big request up into several smaller ones. However, the JSON for the "Export Web Map Task" can't be split up.
So if there are any limitations to the JSON length, please let me know. So I can plan ahead and maybe look for alternative ways to implement my application.
