Hi everyone, I am trying to figure out how to build a post string, and then user header to post it. I've done some research and I am not getting very far. Basically what I'm doing is taking POST items, then validating them, scrubbing them, and rebuidling the post string and trying to resubmitt it using headers(). I'm getting this error: ErrorCGI ErrorThe specified CGI application misbehaved by not returning a complete set of HTTP headers. Here is my header code, and the post string below it. I don't have any idea what I'm missing or doing wrong. Any help is appreciated! header( "POST /v2/order_submitorder.php HTTP/1.0" ); header( "Host: new.vtusa.com" ); header( "Content-Type: application/x-www-form-urlencoded" ); header( "Content-Length: " . strlen( $post_string ) ); header( $post_string ); Quote Management System v3.00.0903PCompanyName=&PFirstName=Dan&PLastName=Joseph&PAddress1=123 Street&PAddress2=&PCity=Northville&PState=MI&PZipCode=48167&PEmailAddress= djoseph@xxxxxxxxxxxxxx&PPhone=2485551212&PCellPhone=2485521212&PFax=&OFirstName=Jack&OLastName=Mother&OAddress1=456 Avenue&OAddress2=&OCity=Omaha&OState=Ne&OZipCode=68101&OPhone=248889999&OCellPhone=2487889999&DFirstName=Yohan&DLastName=Jacques&DAddress1=789 Boulevard&DAddress2=&DCity=Northville&DState=Mi&DZipCode=48167&DPhone=5867772222&DCellPhone=5866772222&VehicleVIN=1234567890ABCDEFG&VehicleYear=2007&VehicleMake=Honda&VehicleModel=Civic&VehicleColor=Grey&VehicleMiles=234234&ordersubmit=Submit Order&UserID=90&QuoteID=427 -- -Dan Joseph www.canishosting.com - Plans start @ $1.99/month.
