/* changelog:
|
|
2001-07-05
|
|
- detection of character encoding in Content-Type header. server
|
|
will now call the soap_parser object with the specified encoding
|
|
- server will now return the Content-Type header with the sender's encoding type specified
|
|
must still learn more bout encoding, and figure out what i have to do to be able to
|
|
make sure that my response is *actually* encoded correctly
|
|
2001-07-21
|
|
- force proper error reporting for windows compatibility
|
|
2001-07-27
|
|
- get_all_headers() check for windows compatibility
