Does anyone know how I can disable ETag on IIS 7?

Microsoft doesn't make it easy. In fact, the only way I've found to do it requires installing a 3rd party plugin. At that point, the performance benefit of removing etags is questionable.

As I answered here (different question, same answer):

Open your IIS manager, click on the server, and go to HTTP Response Headers. Click the "Add..." button, and under name, enter:

ETag

(case sensitive). Under Value, enter

""

(thats two double quotes)

And ETags begone!

  • Even after doing that it still writes ETag:·"9111cdf83dc3cb1:0","" – Chirag Feb 3 '11 at 1:03
