After 'upgrading' my SOAP application from 0.55 to 0.60 I lost the facilitity of compression. The following HTTP protocol shows the differences between 0.55 and 0.60. --------------------------------------------------------- The original (0.55/0.55) SOAP application behaviour: Request from 0.55 client ... POST / HTTP/1.1 TE: deflate,gzip;q=0.3 Connection: TE, close Accept: text/xml Accept: multipart/* Accept-Encoding: deflate Host: localhost:22221 User-Agent: SOAP::Lite/Perl/0.55 Content-Encoding: deflate Content-Length: 20958 Content-Type: text/xml; charset=utf-8 SOAPAction: "urn:SOAPSvc/Master/Repository#save" Response from 0.55 server ... HTTP/1.1 200 OK Date: Mon, 14 Nov 2005 21:30:14 GMT Server: libwww-perl-daemon/1.36 Content-Encoding: deflate Content-Length: 20943 Content-Type: text/xml; charset=utf-8 SOAPServer: SOAP::Lite/Perl/0.55 Compression works (0.55/0.55) - OK! --------------------------------------------------------- The mixed version (0.55/0.60) SOAP application behaviour: Request from 0.55 client ...

HTTP/1.1 200 OK Date: Mon, 14 Nov 2005 21:39:25 GMT Server: libwww-perl-daemon/1.36 Content-Encoding: deflate Content-Length: 20931 Content-Type: text/xml; charset=utf-8 SOAPServer: SOAP::Lite/Perl/0.60 Compression works (0.55/0.60) - OK! --------------------------------------------------------- The mixed version (0.60/0.55) SOAP application behaviour: Request from 0.60 client ... POST / HTTP/1.1 TE: deflate,gzip;q=0.3 Connection: TE, close Accept: text/xml Accept: multipart/* Accept-Encoding: gzip Host: localhost:22221 User-Agent: SOAP::Lite/Perl/0.60 Content-Encoding: gzip Content-Length: 662 Content-Type: text/xml; charset=utf-8 SOAPAction: "urn:SOAPSvc/Master/Repository#save" Response from 0.55 server ...

POST / HTTP/1.1 TE: deflate,gzip;q=0.3 Connection: TE, close Accept: text/xml Accept: multipart/* Accept-Encoding: gzip Host: localhost:22221 User-Agent: SOAP::Lite/Perl/0.60 Content-Length: 1743 Content-Type: text/xml; charset=utf-8 SOAPAction: "urn:SOAPSvc/Master/Repository#save" Response from 0.60 server is now ... HTTP/1.1 200 OK Date: Mon, 14 Nov 2005 21:53:14 GMT Server: libwww-perl-daemon/1.36 Content-Length: 682 Content-Type: text/xml; charset=utf-8 SOAPServer: SOAP::Lite/Perl/0.55 No compression (0.60/0.55) at all! --------------------------------------------------------- The 'upgraded' (0.60/0.60) SOAP application behaviour: Request from 0.60 client ... POST / HTTP/1.1 TE: deflate,gzip;q=0.3 Connection: TE, close Accept: text/xml Accept: multipart/* Accept-Encoding: gzip Host: localhost:22221 User-Agent: SOAP::Lite/Perl/0.60 Content-Encoding: gzip Content-Length: 662 Content-Type: text/xml; charset=utf-8 SOAPAction: "urn:SOAPSvc/Master/Repository#save" Response from 0.60 server ... HTTP/1.1 415 Unsupported Media Type Date: Mon, 14 Nov 2005 22:07:03 GMT Server: libwww-perl-daemon/1.36 Compression will not work (0.60/0.60) and Request will be repeated from 0.60 client ... POST / HTTP/1.1 TE: deflate,gzip;q=0.3 Connection: TE, close Accept: text/xml Accept: multipart/* Accept-Encoding: gzip Host: localhost:22221 User-Agent: SOAP::Lite/Perl/0.60 Content-Length: 1743 Content-Type: text/xml; charset=utf-8 SOAPAction: "urn:SOAPSvc/Master/Repository#save" Response from 0.60 server is now ... HTTP/1.1 200 OK Date: Mon, 14 Nov 2005 22:07:04 GMT Server: libwww-perl-daemon/1.36 Content-Length: 730 Content-Type: text/xml; charset=utf-8 SOAPServer: SOAP::Lite/Perl/0.60 No compression (0.60/0.60) at all! --------------------------------------------------------- Conclusions: The 0.55 client sends Content-Encoding: deflate which will be supported by 0.55 and 0.60 server. The 0.60 client sends Content-Encoding: gzip which will *not* be supported by 0.55 and 0.60 server. Questions: - Why was 'deflate' replaced through 'zgip'? - How could the compression be used under 0.60/0.60? - Is the content encoding 'gzip' buggy? tom thw@cpan.org
