CURL.SetOptionDNSCacheTimeout
Component: CURL
Version: 2.5
Mac OS X: Works
Windows: Works
MBS( "CURL.SetOptionDNSCacheTimeout"; handle; value )
Parameters
| Parameter | Description | Example value |
|---|---|---|
| Handle | The CURL session handle. | $curl |
| Value | The new timeout in seconds. | 60 |
Result
Returns "OK" on success.
Description
Sets the DNS Cache Timeout in seconds.Name resolves will be kept in memory for this number of seconds. Set to zero to completely disable caching, or set to -1 to make the cached entries remain forever. By default, libcurl caches this info for 60 seconds.
The name resolve functions of various libc implementations don't re-read name server information unless explicitly told so (for example, by calling res_init(3)). This may cause libcurl to keep using the older server even if DHCP has updated the server info, and this may look like a DNS cache issue to the casual libcurl-app user.
Feedback: Report problem or ask question.
