WMSLayer bypasses proxy when using GetFeatureInfo.

Hi,

We are displaying an ESRI for JS 4.17 map on an Angular 9 spa within an asp.net web app.

We are trying to access EAGLE-I, WMS layer within our application.

In our asp.net application, we have the ESRI proxy downloaded from https://github.com/Esri/resource-proxy.

Our proxy configuration for the EAGLE-I url looks like this:

<serverUrl url="https://eagle-i.doe.gov" matchAll="true" useAppPoolIdentity="false" accessToken="secret-token-number" tokenParamName="eiApiKey" rateLimit="-1" rateLimitPeriod="60" />

Loading a layer works perfectly. The WMS url is correctly forwarded through our proxy: http://localhost/SOCCSWebClient/gisapi/proxy.ashx?https://eagle-i.doe.gov/api/mapservices/geoserver/ows?width=1479&height=541&bbox=-18183495.26887799%2C2146991.791759475%2C-3713048.5701585496%2C7440103.126449953&format=image%2Fpng&request=GetMap&service=WMS&styles=&transparent=true&version=1.3.0&crs=EPSG%3A3857&layers=eagle-i%3Acoal_mines.

But, when I click a feature from the map to view it’s popup, I get 401 error because the GetFeatureInfo call, first uses the proxy, but executes again without the proxy.

What I see in the network tab of chrome's developer tools is the WMSLayer calls correctly the first time and then calls again, incorrectly a second time.

Good call:

http://localhost/SOCCSWebClient/gisapi/proxy.ashx?https://eagle-i.doe.gov/api/mapservices/geoserver/ows?bbox=-18183495.26887799%2C2171451.6408107243%2C-3713048.5701585487%2C7415643.277398704&format=image%2Fpng&request=GetFeatureInfo&service=WMS&styles=&transparent=true&version=1.3.0&crs=EPSG%3A3857&layers=eagle-i%3Acoal_mines&query_layers=eagle-i%3Acoal_mines&info_format=text%2Fhtml&feature_count=25&width=1479&height=536&I=704&J=373

Quickly negated by bad call:

https://eagle-i.doe.gov/api/mapservices/geoserver/ows?bbox=-18183495.26887799,2171451.6408107243,-3713048.5701585487,7415643.277398704&format=image/png&request=GetFeatureInfo&service=WMS&styles=&transparent=true&version=1.3.0&crs=EPSG:3857&layers=eagle-i:coal_mines&query_layers=eagle-i:coal_mines&info_format=text/html&feature_count=25&width=1479&height=536&I=704&J=373

Any suggestion on how to fix this would be appreciated.

Thanks in advance.
