I've got a problem in my application stack. .Net website SiteA on server-farm A calles Site-B website on server-farm B throught a Citrix Netscaler Load Balancer on a static file ressource, in our case a .json file. Sometimes we get a http-405 back.
I've used MS Network monitor on Server-Farm A, and can see the valid http-request going towards server-farmB.

GET /asset-manifest.json HTTP/1.1..Host
On Server-Farm B, i also used MS Network Monitor, and here i can also see the valid http-request entering the destination server.

GET /asset-manifest.json HTTP/1.1..Host:
But when doing a TRACE in IIS, the request-Verb is reduced from GET to 'T'. Our IIS installation is completly generic, only URLRewrite 2.0 is installed.

SiteId="22", AppPoolId="<domain>", ConnId="1612948779", RawConnId="0", RequestURL="<domain>:80/asset-manifest.json",RequestVerb="T"
Anyone has any idea why this is happening and how to solve this?
