Plus is replaced with space when sending data with HttpWebRequest

Hi!

So, I have problem as described in subject.

Here is source code:

Public Sub SendFormData(ByVal sUrl As String, ByVal sFormData As String) As
String

Try

Dim sbHTMLResponse As New StringBuilder

Dim byte_data As Byte() = Encoding.UTF8.GetBytes(sFormData.ToString)

Dim NewRequest As HttpWebRequest = CType(WebRequest.Create(sUrl),
HttpWebRequest)

NewRequest.Method = "POST"

NewRequest.ContentType = "application/x-www-form-urlencoded"

NewRequest.ContentLength = byte_data.Length

NewRequest.AllowAutoRedirect = False

Dim oNewRequestStream As Stream = NewRequest.GetRequestStream()

oNewRequestStream.Write(byte_data, 0, byte_data.Length)

oNewRequestStream.Close()

Catch ex As Exception

Response.Write("Exception happend!")

End Try

End Sub

I have sent this string:

sgGCXlQlpbn+rBOotb8jiZ/xVrUXBOl2kx9LGsjrmtOoazaf85A6ryXiuB+OglO6OWJ+gUT7M 4v+ilaF8kmrOP5JqxYwODcPVhI4UIbYhWeJ4JibpDxpbaf2kVL eU/0Z7iwM9XgR9ho4

Other applications (asp.net application on same server, asp.net application
on other server and php application on other server) receive this string
(please note that the '+' becomed space):

sgGCXlQlpbn rBOotb8jiZ/xVrUXBOl2kx9LGsjrmtOoazaf85A6ryXiuB OglO6OWJ gUT7M4v
ilaF8kmrOP5JqxYwODcPVhI4UIbYhWeJ4JibpDxpbaf2kVLeU/0Z7iwM9XgR9ho4

Any ideas?

Only connection I have found between '+' and space is in some old cgi
article about URL encoding where space is coded as '+'. But this is FORM
POST method... And '+' is obviously coded as space.

Thanx in advance!

Hi Alex!

This is article aout QueryString and I cannotuse GET method, I must use FORM
POST method to send this data. I'm sending data to credit card company and
I should send them some kind of hash wich may contain plus sign. I have
server side hash calcualtion so I send those data with HttpWebRequest object
from server. When I send those data, they receive my data with spaces except
plus signs.

I', out of ideas... why should "+" be encoded as white space.... it should
be vice versa... :(

forget my last post.... thanx man, this thing works!
