I have a web site deployed to IIS 7. One page it is has 15+ .js files linked to it.

Last two files referenced in <head> tag (loaded last) get 403 forbidden response from server.

I have enabled FailedRequestTracing and have been able to see a detailed error code which is 403.502.

I suppose over a very short period of time I am just pulling to much and the IIS blocks me.

Is there a way I can configure the limit to enable larger number of requests and get rid of 403.502 error?

Solved it. It turns out I had IIS Dynamic IP Restrictions plugin installed on the web server, with default configuration set to 20 max requests per 200 milliseconds. After increasing the limit the problem was gone.
