Portal 10.4 Request.Path error on IIS

LevinConway — Wed, 24 Feb 2016 21:31:28 GMT

Greetings,

I have just updated one of our development portals from 10.3.1 to 10.4. The portal comes up OK, but when trying to switch between top menu items, the following error is thrown in Internet Explorer 11:

A potentially dangerous Request.Path value was detected from the client (:).

We are running our portal (and IIS-based web adaptor) on Windows Server 2012 R2. Some research indicated that ESRI moved to .NET 4.x at this release, which has more secure request validation in ASP.NET.

The good news is that this error only affects IE configurations that have Compatibility View enabled. The bad news is that many organizations (including ours) have this turned on by default for intranet applications needing earlier versions of IE. I have logged an ESRI case on this, but if anyone experiences this error, turning Compatibility View off is the workaround.

Thanks for this... I am about to bring up our 10.4 dev Portal and of course like any big org, we have to have computability view turned on.

I wonder if there is anyway in IIS to lower the security or tweak a setting to avoid the error?

Please note that ESRI support has been able to reproduce the issue and is now tracking the following issue as a bug:

hi , same problem have and when is not in compatibility setting but is with this situation

portal is 10.4

added to domain

installed and using web adaptor

turned on Active Directory Authentication

SSL certificate ( with certificate authority ) and name is FQDN

and when we add the url of portal to local intranet ( with FQDN and without FQDN)

when open home of portal is ok but when click in top Navigation menu show same error.

we show the link in url is appended .

example we are in home tab and click on gallery the resuts is error and url is example modified:

https://portal.domain.com/arcgis/home/https://portal.domain.com/arcgis/home/gallery.html

when using only direct links working.

when removing from local intranet site working without this problem.

we tested to add separately and in trusted sites and local intranet - same results.

We think the problem is in the code of Top Navigation Menu buttons , because inside not showed this problems.

example when we are in map viewer ( in portal ) and using in top menu not have this problem all work

BTW - we have had all sorts of bizzare issues with IE when running in compatbility mode.

Most were related to moving between menu items.

Doubled up URLs (it would show the selected menu item path and then prepend the home path)

And other odd things.

I was told by Esri that:

Compatibility mode was introduced at IE8, and essentially tells your browser to treat web sites as if it was using IE7. Portal for ArcGIS does not support IE7.

Supported web browsers

For the best performance in the portal website, use the latest browser versions listed below. The scene viewer has its own browser and hardware requirements. Some of the common clients of Portal for ArcGIS have different requirements. See their documentation for details.
• Microsoft Internet Explorer 9 and higher.
• Microsoft Edge
• Mozilla Firefox (version 10 or later)
• Google Chrome (version 10 or later)
• Safari
• iOS Safari
• Android Browser
• Chrome for Android

Yep, it's not optimal to have to turn off compatibility mode but there it is. Ongoing browser wars, what can you do.

hi,

I tested with IE11 version 11.0.29 - Doubled up URLs.

Google Chrome browser - all is correct

The problem with Doubled up URLs is with IE + local intranet.

when add compatibility mode not have other effects in my current configuration

Works fine in Firefox 42.0, but having double URLS when switching menus in IE 11.0.29. Compatibility Mode seems to have no impact on fixing the error (either on or off).

You might try upgrading IE? My version is 11.0.96.

Are you running in Enterprise mode?

I can't recall for sure, but I think the URL doubling at times appeared to be related to the security settings.

Try toggling these settings?

"Allow access to the Portal through HTTPS only"

"Allow anonymous access to your Portal"

Re: Portal 10.4 Request.Path error on IIS

JoeTack — Mon, 02 May 2016 13:36:44 GMT

Tried all possible combinations of those security settings within portal. Also tried changing the bindings in IIS. Still having the double URLs in IE 11.

We're working around this by updating the web.config as:

<system.webServer>

</customHeaders>

</httpProtocol>

Re: Portal 10.4 Request.Path error on IIS

LevinConway — Mon, 02 May 2016 19:50:40 GMT

Thanks Randall. I have tried this edit in web.config on the dev portal and restarted IIS. On the few IE 11 client PCs tested so far, the error no longer displays with compatibility mode on. Will post an update later when more are tested.

Joe:

I just checked some notes and for us, the doubling went away when we removed the compatibility setting.

This meant removing our domain and unchecking the intranet box on the compatibility setting dialogue box.

I do now that on the servers themselves, I had to mess with the security settings in IE to get things to work correctly.

That was not a doubling thing though.

Are you using a CA or a self-signed cert?

How about the AGS setup?

FWIW - We're on HTTPS only on Portal and on ArGIS Server.

I also recall that in IIS I had to set the SSL Settings to ignore Client certificates.

However, this was related to a 403 permissions error when trying to get to Portal home page.

Sorry for the delay in response. Juggling too many objects right now. I have

no control of our internet explorer policy as I work on a Federal network for

the Army. They specify the appropriate version...

For compatibility settings, no websites are in the compatibility list and

Display intranet sites in compatibility view is unchecked by security policy.

For portal security settings, I have tried all possible combinations of HTTPS

only and allow anonymous access. Currently don't have the https only checked

and allow anonymous is checked.

ArcGIS rest services can be accessed either by http or https.

I have one everything from SQL server express to portal on the same virtual

machine.

I have one web adaptor configured for ArcGIS Server and another for Portal

A Self signed certificate is being used.

Thanks,

Joe

Still not getting this to work. perhaps you can supply the full config file with this code in it.

Re: Portal 10.4 Request.Path error on IIS

ChristineLarsen — Wed, 25 May 2016 13:18:45 GMT

The web.config file is found here: C:\inetpub\wwwroot\<webadaper>

Find this section (in our file it starts at line 250):

<!--

The system.webServer section is required for running ASP.NET AJAX under Internet

Information Services 7.0. It is not necessary for previous version of IIS.

-->

<system.webServer>

Add the code provided by Randall.

still not working. this is fine on the server running the web adaptor. our folks here think security on local intranet settings also play a factor.

let me define 'not working'. yes the double url no longer appears from address , but the page also disappears. i have to refresh 3 times to MAYBE see the full page.

we left the compatibility view on, and tried to change the local intranet settings. same result. the address not doubled but page not displaying properly.

UPDATE ISSUE WAS AN ADD-ON

I have a particular add on that once disabled, resolved the disappearing act. I reset my IE to orginal settings and everything worked. so i went to another machine which had my personal settings and noticed an add-on
