Some characters causing problems in HttpWebRequest

[Peter Afonin]

Hello,

I've created the domain registration system in ASP.NET. I'm using
HttpWebRequest to post the data to the registrar's server. So in the Post
string I'm passing the data like name, address, phone number etc.

The only two fields that are causing problems are the phone and fax fields.
My only guess here is that's because they start with the "+" sign. So the
string looks like this:

strPost=".....&phone=[phone]&fax=[phone]&......"

I guess the combination "=+" doesn't work.

The problem is that I must start any phone number with the "+" sign,
otherwise the registrar's system won't accept it. Any substitutes like
Chr(43) do not help here.

Is there a way to deal with this issue? I guess I should be able to pass any
string, but I had no luck so far.

I would greatly appreciate any help.

Thank you,

You need to URLEncode the parameters. Spaces etc are not permitted in
URLs. You can use:

value = HttpUtility.UrlEncode(value)

to do the necessary conversions.

Hi,

Some characters have special meanings and would cause confusion in a URL
which may result in the data being misinterpreted.
URL encoding is a way of providing a code to represent the textual

Use HttpUtility.UrlEncode( StringToEncode ); to encode data to post

myString = "Name=" + HttpUtility.UrlEncode( "doe" );
myString += "&SurName=" + HttpUtility.UrlEncode( "john" );
Use HttpUtility.UrlDecode( urlToDecode ); to decode data to post
in ASP.net: HttpServerUtility.UrlEncode

String MyURL;
MyURL = "http://www.contoso.com/articles.aspx?title = ASP.NET Examples";
Response.Write( "<A HREF = " + Server.UrlEncode(MyURL) + "> ASP.NET
Examples <br>" );

//NB: MyURL will be encoded as
"http%3a%2f%2fwww.contoso.com%2farticles.aspx%3fti tle+%3d+ASP.NET+Examples"
instead of
"http%3a%2f%2fwww.contoso.com%2farticles.aspx%3fti tle+=+ASP.NET+Examples"

Hello,

Thank you all very much for your suggestions. I'll try them.

But what would happen with the spaces, for instance, in the address? They
are not allowed. I guess they also will be encoded?
