You can do it however you want to do it so long as it is a valid querystring.

For example, you could do ?brand=samsung,123|apple,11&price=100,12|200,

You can choose whatever you want to delimit the values then when you are retrieving Request.QueryString["brand"] you'll then want to use the Split function to break them back out.

Also, this is just an example, make sure to use UrlEncode() to actually encode the url since whatever character you choose as a delimiter may need encoding.

You can use HTML5 Local Storage for this. Otherwise, I would suggest you to fetch these from database on that page and show them.

However, I was checking the Flipkart site. It is sending parameters somewhat like you.
http://www.flipkart.com/laptops/pr?p%5B%5D=facets.brand%255B%255D%3DAsus&p%5B%5D=facets.brand%255B%255D%3DDell&sid=6bo%2Cb5g&q=laptop&ref=f3c96052-246e-479a-83e9-d798d3770845[^].

Here I have selected Asus and Dell as my laptop filters. It has added the parameters in URL only, but they are encoded. So, encode the URL and try to use in this format, if you can. Here %5B%5D is encoded for [].

What help you need? You just need to append appropriate parameter and values in the query.

<pre>  protected void Button1_Click(object sender, EventArgs e)
    {

        ArrayList brandarray = new ArrayList();
        brandarray.Add("brand");
        brandarray.Add("brand2");
        brandarray.Add("brand3");

        ArrayList pricearr1 = new ArrayList();
        pricearr1.Add("price");
            pricearr1.Add("price2");
            pricearr1.Add("price3");
            pricearr1.Add("price4");


            string arry1 = String.Join(",", ((string[])pricearr1.ToArray(typeof(String))));

            ArrayList Attributearray = new ArrayList();
            Attributearray.Add("Attribute");
            Attributearray.Add("Attribute2");
            Attributearray.Add("Attribute3");
            Attributearray.Add("Attribute4");


            string arry12 = String.Join(",", ((string[])Attributearray.ToArray(typeof(String))));


            Response.Redirect("Default.aspx?brand=" + arry + " &amp;price=" + arry1 + " &amp;Discount=" + arry12);
    }</pre>
