|---|
| 19 | 2001-07-04 |
|---|
| 20 | - abstract type system to support either 1999 or 2001 schema (arg, typing still needs much |
|---|
| 21 | solidification.) |
|---|
| 22 | - implemented proxy support, based on sample code from miles lott <milos@speakeasy.net> |
|---|
| 23 | - much general cleanup of code & cleaned out what was left of original xml-rpc/gigaideas code |
|---|
| 24 | - implemented a transport argument into send() that allows you to specify different transports |
|---|
| 25 | (assuming you have implemented the function, and added it to the conditional statement in send() |
|---|
| 26 | - abstracted the determination of charset in Content-type header |
|---|
| 27 | 2001-07-5 |
|---|
| 28 | - fixed more weird type/namespace issues |
