Hi,
We have a strange issue recently with Apache. When we request some webpages (running on apache web server) from our server, if we make the request from Safari, they are loaded instantly. If we load the web page from Chrome or Firefox, it takes approximately 10 minutes to get the response. The same behavior is observed with curl too. After much research, we found that if the User-Agent header has "Mozilla" String in it, the requests are taking time. Response time is normal with below command curl -i -v -H "User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:51.0)" ourserverurl.com curl -i -v -H "User-Agent: Gecko/20100101" ourserverurl.com
Response time is very slow (approximately 3 to 10 minutes): curl -i -v -H "User-Agent: Gecko/20100101 Firefox/51.0" ourserverurl.com curl -i -v -H "User-Agent: Firefox/51.0" ourserverurl.com
We have not upgraded anything recently. But this issue popped up suddenly. Any pointers to resolve the issue will help. Thank you in advance.
It is the same results (same kind of slowness) for all kinds of resources (that can be compressed). We have tried multiple things like adding compress/ gzip header/ removing it etc.. Still the same. It just worked fine if we remove user-agent "Mozilla" string. We have multiple applications running through this server and all of them behaved the same way (same kind of slowness)..
