php - Can I modify the http headers sent via a SOAP request -

i'm having trouble getting soap compression working , after reading documentation service i've realised it's because they've decided ignore http standard , own thing.

basically need able set content-encoding header to:

content-encoding: accept-gzip,accept-deflate 

rather using accept-encoding, they've decided use content-encoding incredibly annoying , there's 0 chance of them changing it. if set compression option in soap client sends

content-encoding: gzip 

which causes soap client throw exception saying "unknown content-encoding".

so possible alter http request gets sent using default php soap client?

maye somebody:

$mode = array (         'soap_version'  => 'soap_1_1', // use soap 1.1 client         'keep_alive'    => true,         'trace'         => 1,         'encoding'      =>'utf-8',         'compression'   => soap_compression_accept | soap_compression_gzip | soap_compression_deflate,         'exceptions'    => true,         'cache_wsdl'    => wsdl_cache_none,         'stream_context' => stream_context_create (              array (                 'http' => array('header' => 'content-encoding: xxxxxxx'),             )         )     );      // initialize soap client     $client = new loenviosoapclient ( $this->wsdl, $mode );
