Kristian Kraljic created HTTPCLIENT-2011:
--------------------------------------------
Summary: Encoded plus sign (%2B) is not preserved when URI
contains an encoded forward slash (%2F)
Key: HTTPCLIENT-2011
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2011
Project: HttpComponents HttpClient
Issue Type: Bug
Affects Versions: 4.5.9
Reporter: Kristian Kraljic
This issue is likely related to issue HTTPCLIENT-1968.
For URIs that contain an encoded forward slash (%2F), encoded plus signs (%2B)
are no longer preserved when the HTTP client executes. The behaviour is as
expected when no endocded forward slash is part of the URI. In my tests, in
case the URL contains an encoded forward slash, all encoded plus signs will be
replaced by unencoded ones, leading to them beeing replaced with a space when
decoding the URI:
{noformat}
Expected behaviour w/o encoded forward slash:
Foo%2BBar -> Foo+Bar
Foo%2BBar%2ABaz -> Foo+Bar*Baz
Unexpected behaviour w/ encoded forward slash:
Foo%2BBar%2FBaz -> Foo Bar/Baz
Foo%2BBar%2ABaz%2FQux -> Foo Bar*Baz/Qux
{noformat}
Similar to the issue HTTPCLIENT-1968, downgrading the HTTP Client to 4.5.2
solved the issue for me. Therefore I would suggest either the same decoding /
re-encoding step as in issue HTTPCLIENT-1968 or even the fix of HTTPCLIENT-1968
causes this behaviour.
