My problem arises when:

• matrix job axis contains parameters with "/" sign (like: paths)
• Jenkins is proxied by Apache like in: JENKINS-12623

After run, lins to subtasks look like:

http://localhost:8080/job/matrixUrlProblem/PATH=%2FmyPath%2Ffile1/

Note that path parameter is encoded "/" changed to "%2F"

Everything works fine, but when I want to use http://jenkins.my.organization.com address, it doesn't work. Depending on AllowEncodedShlashes (see https://httpd.apache.org/docs/2.4/mod/core.html#allowencodedslashes ) setting results are differn:

• AllowEncodedShlashes Off: blocked by Apache
• AllowEncodedSlashes NoDecode: ERROR 404: Problem accessing /job/matrixUrlProblem/PATH=%252FmyPath%252Ffile1/ (% from original URL encoded as "%25")
• AllowEncodedSlashes On: ERROR 404: Problem accessing /job/matrixUrlProblem/PATH=/myPath/file1/ ("%2F" decoded back to /)

The easiest way is to classify it as problem outside Jenkins, but I hope you'll suggest some solution except "fix Apache"
