ExportMap Temporary File Lifespan

TylerOhlsen — Fri, 13 May 2011 15:03:15 GMT

When calling ExportMap with a JSON return format, an HREF field is included with a URL to the image you requested. I'm assuming this is a generated temporary file. I would like to know how long that file exists.

Is its lifespan a duration since it was generated or are those temporary files purged at a specific time of day (like 4am)? If purged at a specific time, if a map was requested 1 minute before the purge, would it be purged 1 minute later?

Thanks,
Tyler

Tyler,

it depends on the maxFileAge configured for the arcgisoutput directory. Please see this help topic for more information .http://help.arcgis.com/en/arcgisserver/10.0/help/arcgis_server_dotnet_help/index.html#//0093000000mq000000.htm

I see, thanks for the information. Can you tell me what the maxFileAge is set to on ESRI's hosted services (such as World Imagery)?

Thanks again,
Tyler
