An LTM Specialist configures a virtual server to load balance to a pool of FTP servers. File transfers are failing. The virtual server is configured as follows:
ltm virtual ftp_vs {
destination 10.10.1.103:ftp
ip-protocol tcp
mask 255.255.255.255
pool ftp_pool
profiles {
tcp { }
}
vlans-disabled
}
Which change will resolve the problem?
An LTM Specialist has a OneConnect profile and HTTP profile configured on a virtual server to load balance an HTTP application.
The following HTTP headers are seen in a network trace when a client connects to the virtual server:
Clientside:
GET / HTTP/1.1
Host: 192.168.136.100
User-Agent: Mozilla/5.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-EncodinG. gzip, deflate
Connection: keep-alive
Serverside:
HTTP/1.1 200 OK

Vary: Accept-Encoding
Content-EncodinG. gzip

Content-TypE. text/html
The LTM Specialist notices the OneConnect feature is working incorrectly.
Why is OneConnect functioning incorrectly?
The LTM Specialist is writing a custom HTTP monitor for a web application and has viewed the content by accessing the site directly via their browser. The monitor continually fails. The monitor configuration is:
ltm monitor http /Common/exampleComMonitor {
defaults-from /Common/http
destination *:*
interval 5
recv "Recent Searches"
send "GET /app/feed/current\?uid=20145 HTTP/1.1\\r\\nHost: gzip, deflate\\r\\nConnection: close\\r\\n\\r\\n"
time-until-up 0
timeout 16
}
A trace shows the following request and response:
Request:
GET /app/feed/current?uid=20145 HTTP/1.1
Host
Accept-Encoding gzip, deflate
Connection: close
