.SH NAME
|
||
|
|
CURLOPT_MAXAGE_CONN \- max idle time allowed for reusing a connection
|
||
|
|
.SH SYNOPSIS
|
||
|
|
.nf
|
||
|
|
#include <curl/curl.h>

||
|
|
|
||
|
|

.SH DESCRIPTION
|
||
|
|
Pass a long as parameter containing \fIage\fP \- the maximum time in seconds
|
||
|
|
allowed for an existing connection to have been idle to be considered for
|
||
|
|
reuse for this request.
|
||
|
|
|
||
|
|
The "connection cache" holds previously used connections. When a new request
|
||
|
|
is to be done, libcurl considers any connection that matches for reuse. The
|
||
|
|
\fICURLOPT_MAXAGE_CONN(3)\fP limit prevents libcurl from trying too old
|
||
|
|
connections for reuse, since old connections have a higher risk of not working
|
||
|
|
and thus trying them is a performance loss and sometimes service loss due to
|
||
|
|
the difficulties to figure out the situation. If a connection is found in the
|
||
|
|
cache that is older than this set \fIage\fP, it is closed instead.
|
||
|
|
.SH DEFAULT
|
||
|
|
Default maximum age is set to 118 seconds.
