24:
25: .SH NAME
26: CURLOPT_MAXAGE_CONN \- max idle time allowed for reusing a connection
27: .SH SYNOPSIS
28: #include <curl/curl.h>
29:
30: CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXAGE_CONN, long maxage);
31: .SH DESCRIPTION
32: Pass a long as parameter containing \fImaxage\fP - the maximum time in seconds
33: that you allow an existing connection to have to be considered for reuse for
34: this request.
35:
36: The "connection cache" that holds previously used connections. When a new
37: request is to be done, it will consider any connection that matches for
38: reuse. The \fICURLOPT_MAXAGE_CONN(3)\fP limit prevents libcurl from trying
39: very old connections for reuse, since old connections have a high risk of not
40: working and thus trying them is a performance loss and sometimes service loss
41: due to the difficulties to figure out the situation. If a connection is found
42: in the cache that is older than this set \fImaxage\fP, it will instead be
43: closed.
44: .SH DEFAULT
45: Default maxage is 118 seconds.
46: .SH PROTOCOLS
47: All
48: .SH EXAMPLE
49: .nf
50: CURL *curl = curl_easy_init();
51: if(curl) {
52: curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
53:
54: /* only allow 30 seconds idle time */
55: curl_easy_setopt(curl, CURLOPT_MAXAGE_CONN, 30L);
56:
57: curl_easy_perform(curl);
58: }
59: .fi
60: .SH AVAILABILITY
61: Added in libcurl 7.65.0
62: .SH RETURN VALUE
63: Returns CURLE_OK.
