PrintTask not working with proxy.ashx, 500 Error

DaveHighness1 — Wed, 21 Jan 2015 22:42:15 GMT

I am using the ArcGIS Server Javascript API PrintTask Execute with the proxy.ashx file based proxy. The PrintTask is Synchronous and often takes 30 seconds or more to complete. I am getting a 500 Error from the proxy.ashx after about 30 seconds. If I turn off a bunch of the layers and run it, it takes less than 30 seconds and completes. I have not found a way to keep the proxy.ashx from timing out. Any ideas?

Thanks, Dave

The proxy.ashx is working fine with all the other requests.

Gad, I wish PrintTask.execute() used Post instead of Get! Sticking web maps into the URL seems kinda ridiculous!

I figured out the problem. I did two things:

Added this to the web.config of the proxy.ashx application:

<system.web>

<system.web>

</configuration>

This site is also behind an IIS Reverse Proxy which had a request timeout of 30 seconds. So I went to the Server Farm setting on the proxy machine and changed the proxy timeout from 30 seconds to 180 seconds.

Between the two settings it now works.
