How to add header in each request?

[Amogh Shah]

I successfully implemented CEF version 31 in my C# application. Now what I want is, I want to add an request header in each request. I have checked the method OnBeforeBrowse(IWebBrowser browser, IRequest request, NavigationType naigationvType, bool isRedirect) but I cannot change Headers of IRequest request object.

Is their any way to do this?

Serendipitous. There is a recent pull request for CefSharp3 to deal with this (pull request 413). Refresh from the master branch then use OnBeforeResourceLoad() like this:

        public bool OnBeforeResourceLoad (IWebBrowser browser, IRequestResponse requestResponse)

        {

            // The collection returned here is a copy of the collection held by

            // CEF, changing this collection will have no effect until the

            // Request's Headers property is set.

            var headers = requestResponse.Request.Headers;

            headers["User-Agent"] = "My User Agent";

            // Must set the headers back on the property, we get a copy of the

            // headers above not a reference.

            requestResponse.Request.Headers = headers;

            // False means continue.

            return false;

        }
