With these it helps The problem is & is not a "query string encoding" - it is an XML/HTML entity-escape and the server (correctly) breaks the id parameter at the & in the query string. The server cares about URLs, not XML.
See Percent Encoding (aka URI encoding) for how to correctly1 write the URL which is

hop of those help? I want to add some querystrings to httpwebrequest, however I cannot find any property? I remembered there is a QueryString dictionary which I can use before. , The best way to add a query string is as follows:
code :
var targetUri = new Uri("http://www.example.org?queryString=a&b=c");
var webRequest = (HttpWebRequest)WebRequest.Create(targetUri);

var webRequestResponse = webRequest.GetResponse();

fixed the issue. Will look into that further I believe your error is not on the fetching, but on the writing of the new file, so instead of using File.WriteAllText, you perhaps should look at:
How to write out a text file in C# with a code page other than utf-8?
code :
using (StreamWriter sw = new StreamWriter(File.Open(myfilename, FileMode.Create), Encoding.WhateverYouWant))
    sw.WriteLine("my text...");

To fix the issue you can do /* Write like this You must add you variable as postdata */ var request = (HttpWebRequest)WebRequest.Create("http://www.example.com/recepticle.aspx");
code :
var postData = "thing1=hello";
    postData += "&thing2=world";
var data = Encoding.ASCII.GetBytes(postData);

request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;

using (var stream = request.GetRequestStream())
    stream.Write(data, 0, data.Length);

var response = (HttpWebResponse)request.GetResponse();

var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();

I think the issue was by ths following , This is not working because your current RewriteRule only matches root page /. You need to match myscript/script1.php
code :
RewriteEngine On
RewriteCond %{HTTP_HOST} domain1\.com$ [NC]
RewriteCond %{QUERY_STRING} do=login [NC]
RewriteRule ^myscript/script1\.php$ https://domain2.com/script1.php?%{QUERY_STRING} [R=301,L]

I wish this help you The QueryString property returns a NameValueCollection object that maps the querystring keys to fully-decoded values.
You need to write Request.QueryString["FileName"].
