I use scripts (using arcrest) to zip my hosted features and download them. The zips are placed in the 'my content' folder and have names in the form ddmm_hhmm_featurename__layername.zip
All works well except for two feature layers; these are zipped correctly and visible in 'my content' but cannot be downloaded and a HTTP error 400 'bad request' is logged.
Since these two have the longest names of my batch, 46 and 54 characters, I suspect there is a maximum request length for the post I make.
Has anyone seen this error before when requesting from the agol? Does anyone know of a maximum? I am led to believe the maximum post length is a setting in the webserver but I might be mistaken.
