How to send HTTP POST query string consist of & and NULL character

[bidesh]

Hi All,

I want to send HTTP POST message to my web server method. But my query string consist of '&' and NULL.

I am using wininet classes method such as,

HttpSendRequest();

My query string for the POST request is mentioned below.

POST /Service/Service.asmx/CheckValidity HTTP/1.1
Host: localhost
Content-Type: application/x-www-form-urlencoded
Content-Length: length

Test1=<data including '&' and NULL>

Body part like this "Ab1Cde4&adjdkNULLdfa!#A

When I send this request to web server, web server does not get the same string rather the string gets truncated.

I am testing this with a web server build locally using ASP.NET

Please help me how I can solve this

Thanks,
Bidesh
