Perl: setting content-type in continuation

["Leonard den Ottolander" <leonardjo hetnet nl>]

		Hi all,

 I am working on a meta search engine for books. I do have a small problem 
with one of the search sites I am querying. It seems the search script on this 
site is testing the http headers. With LWP:UserAgent I can create http 
requests, but the content-type is being set in the first packet instead of in 
the continuation. Here are extracts of four dumped packets to illustrate this.
 The browser (Netscape 4.76) generates the following header (only partially 
included):
 request:
    Connection: Keep-Alive\r\n
    User-Agent: Mozilla/4.76 [en] (Win98; U)\r\n
    Host: www.biblioroom.com\r\n
    Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png, 
*/*\r\n
    Accept-Encoding: gzip\r\n
    Accept-Language: en\r\n
    Accept-Charset: iso-8859-1,*,utf-8\r\n
 continuation:
Hypertext Transfer Protocol
    Content-type: application/x-www-form-urlencoded\r\n
    Content-length: 153\r\n
    \r\n
    Data (153 bytes)

   0  5744 5f42 5554 544f 4e5f 434c 4943 4b5f   WD_BUTTON_CLICK_ 

 But perl creates the following:
 request:
    User-Agent: Mozilla/4.76 [en] (Win98; U)\r\n  # I faked the user agent
    Content-Length: 153\r\n
    Content-Type: application/x-www-form-urlencoded\r\n
    \r\n
continuation:
Hypertext Transfer Protocol
    Data (153 bytes)

   0  5744 5f42 5554 544f 4e5f 434c 4943 4b5f   WD_BUTTON_CLICK_ 

 Is there a way to make perl set the content-type and -length in the 
continuation packet instead of in the initial packet?
 Thanks,

					Bye,

					Leonard.
