| 23 .TH CURLOPT_MAXAGE_CONN 3 "18 Apr 2019" "libcurl 7.65.0" "curl_easy_setopt options" | |
| 24 .SH NAME | |
| 25 CURLOPT_MAXAGE_CONN \- max idle time allowed for reusing a connection | |
| 26 .SH SYNOPSIS | |
| 27 #include <curl/curl.h> | |
| 28 | |
| 29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_MAXAGE_CONN, long maxage); | |
| 30 .SH DESCRIPTION | |
| 31 Pass a long as parameter containing \fImaxage\fP - the maximum time in seconds | |
| 32 that you allow an existing connection to have to be considered for reuse for | |
| 33 this request. | |
| 34 | |
| 35 The "connection cache" that holds previously used connections. When a new | |
| 36 request is to be done, it will consider any connection that matches for | |
| 37 reuse. The \fICURLOPT_MAXAGE_CONN(3)\fP limit prevents libcurl from trying | |
| 38 very old connections for reuse, since old connections have a high risk of not | |
| 39 working and thus trying them is a performance loss and sometimes service loss | |
| 40 due to the difficulties to figure out the situation. If a connection is found | |
| 41 in the cache that is older than this set \fImaxage\fP, it will instead be | |
| 42 closed. | |
| 43 .SH DEFAULT | |
| 44 Default maxage is 118 seconds. | |
| 45 .SH PROTOCOLS | |
| 46 All | |
| 47 .SH EXAMPLE | |
| 48 .nf | |
| 49 CURL *curl = curl_easy_init(); | |
| 50 if(curl) { | |
| 51 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com"); | |
| 52 | |
| 53 /* only allow 30 seconds idle time */ | |
| 54 curl_easy_setopt(curl, CURLOPT_MAXAGE_CONN, 30L); | |
| 55 | |
| 56 curl_easy_perform(curl); | |
