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.

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...

I would normaly do it with an AJAX call but I need to do a post from WITHIN a PHP function, so when it's doing php stuff ex. function something() { echo 'whatever'; $response = post some data to a ISAPI Extension eg. post to http://domain.com/scripts/app.dll return $response .

[snip] I'm in need of a way to contact an ISAPI Extension from a PHP function. Does anyone know how I would be able to do this? Usually you would post a page to their URL/actionname. Can I do a POST from a PHP function without reloading the page, and get a result back? That's one tall order. Anyone want to give it a shot? [/snip] Do the POST with an AJAX call

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,

The only method that I am aware of is the fsockopen method you mention in your other email -- Jim Lucas

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?
