The setup in which I am working is this way.
I have a proxy through which I connect to internet. say
proxy: 192.168.20.1
default gateway 192.168.20.2
I have an entry in my route to an external server as follows
193.88.125.20 mask 255.255.255.255 gw 192.168.20.1 metric 1
I have developed an application that uses libcurl.
I give command "set http_proxy=" and then run libcurl application.
Now when I give a URL that represents 193.88.125.20,to my libcurl
application, its taking more time to route I guess.
More time to route than what? On a normal LAN a single extra hop makes very
little extra time.
But if I have connected to the internet (any URL) before connecting using
libcurl, it connects much early.
If that extra route thing is the only difference then sure something in your
setup is slowing things down.
Is it that libcurl request is taking more time for its first request?
If you by "first request" mean the first request on a connection that is then
subsequently kept alive and is re-used then yes the first request will then
take noticable longer time.
I have also observed that if ther is a url ABC, then If i connect it using
my application it does not connect immediately, but If i first run it
through media player, internet explorer, and then try using my application,
it works immediately. What could be the issue?
I don't know. I'd suggest running wireshark and strace to see what's going on
under the hood and compare between the faster one and the slower one.
