Hi Team,
I am facing an issue where the Apache requests are malformed and is causing
unusual behavior with the application. We have Webcache servers in front of
Apache webservers. The requests in the Webcache servers are fine but they end
malformed at Apache webservers.
Request in Webcache access log: Request is well formed with GET or POST
(xx.xx.xx.xx - - [Timestamp] "GET /abc/def.htm HTTP/1.1" 501 559 "referrer URL"
"browser/5.0 (Linux;
U; Android 4.2.2; locale; SM-G386F Build/JDQ39) AppleWebKit/534.30 (KHTML,
like Gecko) Version/4.0 Mobile Safari/534.30 " "" 0.009315)
Corresponding request at Apache webserver is malformed as
yy.yy.yy.yy xx.xx.xx.xx - - [timestamp] "jumbled_charactersGET /abc/def.htm
HTTP/1.1" 501 990 "referrer URL" "-"
Some characters are getting added before the actual request ("GET /abc/def.htm
HTTP/1.1") and such requests are not getting blocked/ handled at Apache but are
making it to the Application servers that are behind the webserver.
Please let me know if anyone has faced such an issue and how can this be
handled.
Thanks.
