Question

I use code Request.QueryString[“u”] to read passed URL to my web application. Everything works fine if passed url do not has parameters but for example if such url is submitted

http://mywebapp:80/submit.aspx?u=http://www.submitedurl.com/top_sellers_pdf.php?GoodThru=7-21-2011&comments=This+is+a+test+for+PDF

the Request.QueryString[“u”] return

http://www.submitedurl.com/top_sellers_pdf.php?GoodThru=7-21-2011

and comments=This+is+a+test+for+PDF is ignored.

I understand why this happens no need to explain :), but how this could be solved?

One solution I think would be to surround parameter with quotes. Like this

http://mywebapp:80/submit.aspx?u=“http://www.submitedurl.com/top_sellers_pdf.php?GoodThru=7-21-2011&comments=This+is+a+test+for+PDF”

What other solution could be?

Answer 1

When you build your querystring, use:

var value = HttpUtility.UrlEncode("My querystring with & inside it");
