Why does my large PDF export fail?

About

When exporting reportset, Izenda checks RedirectExports value. If RedirectExports is true, then it returns exported reportset without placing it to session and redirecting response.

Global.asax (C♯)

//main class: inherits DatabaseAdHocConfig or FileSystemAdHocConfig
public class CustomAdHocConfig : Izenda.AdHoc.DatabaseAdHocConfig
{
  // Configure settings
  // Add custom settings after setting the license key and connection string by overriding the ConfigureSettings() method
  public static void InitializeReporting() {
    //Check to see if we've already initialized.
    if (HttpContext.Current.Session == null || HttpContext.Current.Session["ReportingInitialized"] != null)
      return;
    AdHocSettings.LicenseKey = "INSERT_LICENSE_KEY_HERE";
    AdHocSettings.SqlServerConnectionString = "INSERT_CONNECTION_STRING_HERE";
    Izenda.AdHoc.AdHocSettings.AdHocConfig = new CustomAdHocConfig();

    AdHocSettings.RedirectExports = true; // false by default


    HttpContext.Current.Session["ReportingInitialized"] = true;
