Description Mahesh Palaniswamy 2016-03-08 07:28:56 UTC 
For a long URL with %3b (URL encoded characters for semicolon) in the URL path, nocanon option in ProxyPass is ignored. (The URL is for a REST web services call). And, the following warning message is displayed in the error log:

[Tue Mar 08 06:02:22.125148 2016] [proxy:warn] [pid 7204:tid 47095902471936] [client aa.bb.cc.dd:12345] AH01136: Unescaped URL path matched ProxyPass; ignoring unsafe nocanon

Behaviour: This results in a truncated URL reaching the server with truncation happening at the location of semicolon.
