How to programmatically generate a link to open an App Insights KQL query?

krishnachandar Did you ever figure out how to encode and zip the query in javascript? None of the methods below worked for me.

I'm not sure about how to do it in JS, but this is how I do it in C#:

The trick is utf8-encode the query, then gzip it, then base64-encode it, then url-encode it, and finally include it in the url.

        static private string EncodedQuery(string query)
        {
            var bytes = Encoding.UTF8.GetBytes(query);
            using (MemoryStream memoryStream = ExtendedStream.CreateMemoryStream())
            {
                using (GZipStream compressionStream = new GZipStream(memoryStream, CompressionMode.Compress, leaveOpen: true))
                {
                    compressionStream.Write(bytes, 0, bytes.Length);
                }
                memoryStream.Seek(0, SeekOrigin.Begin);
                Byte[] data = memoryStream.ToArray();
                string encodedQuery = Convert.ToBase64String(data);
                return HttpUtility.UrlEncode(encodedQuery);
            }
        }

krishnachandar, I am not a Javascript expert nor I have any code sample to share with you. But you can for sure zip from client side, as there are many libraries out there to perform that. I would however recommend you to first analyze the Azure portal Javascript code itself. When you click on the "Link to query" button, everything happens on the client side. If you manage to understand how that button click event is captured and processed, you'll for sure find the answer to your question in the event processor code itself.
