+.TH CURLOPT_MAXAGE_CONN 3 "18 Apr 2019" "libcurl 7.65.0" "curl_easy_setopt options"
+.SH NAME
+CURLOPT_MAXAGE_CONN \- max idle time allowed for reusing a connection
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXAGE_CONN, long maxage);
+.SH DESCRIPTION
+Pass a long as parameter containing \fImaxage\fP - the maximum time in seconds
+that you allow an existing connection to have to be considered for reuse for
+this request.
+
+The "connection cache" that holds previously used connections. When a new
+request is to be done, it will consider any connection that matches for
+reuse. The \fICURLOPT_MAXAGE_CONN(3)\fP limit prevents libcurl from trying
+very old connections for reuse, since old connections have a high 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 \fImaxage\fP, it will instead be
+closed.
+.SH DEFAULT
+Default maxage is 118 seconds.
+.SH PROTOCOLS
+All
+.SH EXAMPLE
+.nf
+CURL *curl = curl_easy_init();
+if(curl) {
+  curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
+
+  /* only allow 30 seconds idle time */
+  curl_easy_setopt(curl, CURLOPT_MAXAGE_CONN, 30L);
+
+  curl_easy_perform(curl);
+}
+.fi
+.SH AVAILABILITY
+Added in libcurl 7.65.0
+.SH RETURN VALUE
+Returns CURLE_OK.
