QueryTask too long

[FlorianCADOZ]

Hello everyone,

I have a problem with a query that returns me an error saying that the request is too long (error 404.15).

The error is returned by IIS (my web server) and after some internet research I found two parameters to change in IIS but nothing change.

So, I think that it's possible that the problem comes from arcgis server ...

If someone has an idea to solve this problem ... : /

  It fix this type of issue you setup a proxy to handle long query strings:

Hello Robert,

We've already got a proxy installed and working on (mainly for Authentication) but it's not the esri's proxy specified...

How should I proceed to make it ? Working with two proxy ? Only one of them but witch one ? etc.

Thank you in advance for your help

Florain,

  You should only use one. The esri one I linked to handles the long query strings automatically. But I do not know if it will does the authentication that you need or not. It does authentication but I am not sure what your does differently.
