- make DEFAULT sections less repetitive - make historic mentions use HISTORY - generate the protocols section on `# %PROTOCOLS%` instead of guessing where to put it - generate the availability section on `# %AVAILABILITY%` instead of guessing where to put it - make the protocols section more verbose Closes #14227

# NAME
|
|
|
|
CURLOPT_FRESH_CONNECT - force a new connection to be used
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_FRESH_CONNECT, long fresh);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Pass a long. Set to 1 to make the next transfer use a new (fresh) connection
|
|
by force instead of trying to reuse an existing one. This option should be
|
|
used with caution and only if you understand what it does as it may impact
|
|
performance negatively.
|
|
|
|
Related functionality is CURLOPT_FORBID_REUSE(3) which makes sure the
|
|
connection is closed after use so that it cannot be reused.
|
|
|
|
Set *fresh* to 0 to have libcurl attempt reusing an existing connection
|
|
(default behavior).
|
|
|
|
# DEFAULT
|
|
|
|
0
|
|
|
|
# %PROTOCOLS%
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
curl_easy_setopt(curl, CURLOPT_FRESH_CONNECT, 1L);
|
|
/* this transfer must use a new connection, not reuse an existing */
|
|
curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
}
