Discussion & Troubleshooting / \r\n - CRLF too much in http response
« on: May 26, 2008, 06:42:00 PM »
Hi I got a problem with 4images on my IIS with FastCGI installed:
when I make a request to http://localhost/captcha.php i get a red cross in IE.
Internet Explorer is having problems to show the image.
I drilled down and looked into the http response with the wfetch tool.
->I see that in the response right before the image is sent back a see 2 times a "\r\n" (see below)
one is ok as this signals in http that the payload (the image) should begin - however the image starts with another "\r\n" confusing the browser
...

Content-Length: 4940\r\n
\r\n
\r\n

however I found that the duplicate "\r\n" is also sent when requesting the index.php (however the response is text/html and the browser does display it quite fine.)
every page that includes the global.php shows the same problem. A simple <?php phpinfo(); ?> does not show the error (so my php config should be fine)
what is wrong? any ideas?
thanks,
Bernhard
