I came up with a what I presume to be quicker way of doing this by knowing the format. Since the headers always have \r\n after each line, then a blank line before the content I made this little bit of code.

              $explodedResult = explode("\r\n", $result);
               for($i = 0; $i <= count($explodedResult); $i++)
               {
                       if($explodedResult[$i] == "")
                       {
                        return $explodedResult[($i + 1)];
                       }
               }

Yes, it is faster, but sometimes, when loading big sites, not all data is send at once, and then you need to get the content-length from the header and read that many bytes. That's why i've written a little bit longer code :) Tijnema

Whoops, it turned out just to be a line wrapping problem, it was putting an extra space in. I have it working now, but after every request I get back the returning header in my result to it looks like this: HTTP/1.1 200 OK Content-Length: 184 Content-Type: text/html Server: Microsoft-IIS/7.0 Content: Date: Tue, 19 Jun 2007 17:20:04 GMT The resulting page I really wished to be returned. How do I get this not to set the return header in the $result? Or shoudl I just somehow get rid of the header after I get it? I don't know how long it is so I can't do a substring. Ideas?

It has to do something with the way the things are send across the internet, in packages. The manual of fread says that it will read until EOF, the given length or the end of a package... try this code: $post_data = "name=wow&likes=true"; $fp = fsockopen("localhost",8080); fwrite($fp,"POST /Project1.dll HTTP/1.1\r\nHost:localhost\r\nContent-Length:".strlen($post_data)."\r\n\r\n".$post_data); $line = fgets($fp); $length = 0; while($line != "\r\n") { if(strtolower(substr($line,0,15)) == "content-length:") { $length = (int)substr($line,15); } } $result = fread($fp,$length); while(strlen($result) != $length) { $result .= fread($fp,$length-strlen($result)); } echo $result; Ok, above code is untested, and i just written it in gmail, so might be stupid syntax error in it or such.

Like I said, there might be stupid bugs in, this code is better: $post_data = "name=wow&likes=true"; $fp = fsockopen("localhost",8080); fwrite($fp,"POST /Project1.dll HTTP/1.1\r\nHost:localhost\r\nContent-Length:".strlen($post_data)."\r\n\r\n".$post_data); $line = fgets($fp); $length = 0; while($line != "\r\n") { if(strtolower(substr($line,0,15)) == "content-length:") { $length = (int)substr($line,15); $line = fgets($fp); } } $result = fread($fp,$length); while(strlen($result) != $length) { $result .= fread($fp,$length-strlen($result)); } echo $result;

I modified your code to work with what I'm doing and this is what I got: $post_data = "name=wow&likes=true"; $fp = fsockopen("localhost",8080); fwrite($fp,"POST /Project1.dll HTTP/1.1\r\nHost: localhost\r\nContent-Length: ".strlen($post_data)."\r\n\r\n".$post_data); $result = fread($fp,102400); // Reads 100KB, change if you need more echo $result; Now when I try that I get a "Bad Request invalid header name" error. I have an IIS server running localy on port 8080, the Project1.dll is in the root directory, it contains two input components 1 a textfield to type your name, the other a checkbox called likes. What's wrong? Here's it's code: <html> <head> <title>Learning ISAPI</title> </head> <h3>Learning ISAPI!</h3> <form name="isapiform" method="POST" action="/Project1.dll"> <strong>Please enter the following information</strong> <br>Name: <input type="text" name="name"> <br><input type="checkbox" name="likes" value="true" checked> I like ISAPI!<p> <input type="submit" value="View Output"> </form> </html> "Tijnema" <tijnema@gmail.com> wrote in message news:d8269d910706190041m6e5ee258wfb95336b9c362c60@mail.gmail.com...

perform an ajax call the a php script that calls curl to do a post to the ISAPI extension -- Jim Lucas "Some men are born to greatness, some achieve greatness,

Yes, and what's wrong with it? <?php $post_data = "form_a=1&form_b=4"; $fp = fsockopen("www.domain.com",80); fwrite($fp,"POST /scripts/app.dll HTTP/1.1\r\nHost: www.domain.com\r\nContent-Length: ".strlen($post_data)."\r\n\r\n".$post_data); $result = fread($fp,102400); // Reads 100KB, change if you need more ?> That's not too long is it?
