Question

Randomly accessing static files on our web site returns http 504 error status code

From fiddler:

Result Protocol Host URL Body Caching
Content-Type Process Comments Custom
288 504 HTTP
/assets/styles/site1.css 512 text/html
ekrn:700 289 504 HTTP
/assets/styles/rightmenu.css 512
text/html ekrn:700 291 504 HTTP
/assets/scripts/jquery.cookie.js 512
text/html ekrn:700

Fiddler gives information

HTTP/1.1 504 Fiddler – Receive Failure
Content-Type: text/html Connection:
close Timestamp: 08:30:45:8693

ReadResponse() failed: The server did
not return a response for this
request.

The 504 error still appears. This website runs on the same port and ip with over website (multibinding iis function)

Answer 1

Solution was disabling on router HTTP Multiplexing feature.
