Subject: [PATCH] Remove extraneous calls to .strip() in Chunked Encoding
|
|
|
|
To be valid chunked encoding we should not be removing any whitespace as
|
|
the standard does not allow for optional whitespace.
|
|
|
|
If whitespace is encountered in the wrong place, it should lead to a 400
|
|
Bad Request instead.
|
|
|
|
Backport:
|
|
* Patch refresh - no functional change.
