It would help if you would show what you are already using first.

Thanks for responding so quickly.

My first try was:-

NMHTTP1->Post("http://localhost.asptest.asp","name=John");.
This produced the results described in the first post to the group.

Or did you want/need  some different info. In which case could you say what
you mean by 'what you are already using'?

Thanks for your help.

The Netmaster components are buggy and problematic in general.  You would be
better off switching to a different component altogether, such as the HTTP
client found in either Indy (http://www.indyproject.org) or ICS
(http://www.overbyte.be), amongst many other third-party HTTP
implementations that are available.

That is no good idea. Better make it "name=John".

What kind of asp program is that ? Isn't there a webserver ? If it is an
asp script, who wrote it ?

Wasn't it "name%3DJohn" ?

That is perfectly ok. The site states as such: "The data is encoded with + 
sign's and %(hex equivalents).". "%3D" means "=". It is URL encoded.

I did that too. But you better copy and paste it to wordpad because of the
linebreaks.

While testing better send two key=value pairs.

It was ok.

I tested again TNMHTTP posting to some of my webapplications. It does
the job.

Hans.

The server which receives the info is going to get it "url-encoded", a scheme
used to send characters possibly not supported by all "teletypes" in an
encoded form (a percent sign followed by the hex ascii value of the
character). The server will have to decode it, because it is encoded by the
http protocol. For completeness, I attach a couple of routines for handling
the encoding :-

AnsiString mjunescape(AnsiString webstr)
{
  int ii,jj=webstr.Length(),kk,mm; AnsiString
retv="",pschs="0123456789ABCDEF"; char ch;
  for (ii=1;ii<=jj;++ii)
  {
    ch=webstr[ii]; if (ch=='+') { retv+=" "; continue;}
    if (ch!='%') { retv+=ch; continue;}
    if (ii<jj) if (webstr[ii+1]=='%') { retv+="%"; ++ii; continue;}
    if (ii<jj-1)
    {
      kk=pschs.Pos((char)toupper(webstr[ii+1]));
mm=pschs.Pos((char)toupper(webstr[ii+2]));
      if (kk>0 && mm>0) { retv+=(char)((kk-1)*16+mm-1); ii+=2;} else retv+=ch;
    }
  }
  return retv;
}

AnsiString mjescape(AnsiString webstr)
{
  int ii,jj=webstr.Length(); AnsiString retv=""; char ch;
  AnsiString
pschs="ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789*@._-$!'(
)%";
  for (ii=1;ii<=jj;++ii)
  {
    ch=webstr[ii]; if (ch==' ') { retv+="+"; continue;}
    if (pschs.Pos(ch)>0) retv+=ch; else retv+="%"+IntToHex(ch,2);
  }
  return retv;
}
