28 | /* changelog: |
---|
29 | 2001-07-04 |
---|
30 | - abstract type system to support either 1999 or 2001 schema (arg, typing still needs much |
---|
31 | solidification.) |
---|
32 | - implemented proxy support, based on sample code from miles lott <milos@speakeasy.net> |
---|
33 | - much general cleanup of code & cleaned out what was left of original xml-rpc/gigaideas code |
---|
34 | - implemented a transport argument into send() that allows you to specify different transports |
---|
35 | (assuming you have implemented the function, and added it to the conditional statement in send() |
---|
36 | - abstracted the determination of charset in Content-type header |
---|
37 | 2001-07-5 |
---|
38 | - fixed more weird type/namespace issues |
---|
