pckg_expires_index
Configures the expiration behavior for media index files in the Kaltura Media Framework.
Description
The pckg_expires_index directive is utilized in the Kaltura Media Framework's NGINX module to set the expiration time for media index files. When a client requests media content, it may require the associated index files to manage streaming and playback correctly. By using this directive, you can specify how long the media index files should be cached by both clients and intermediate cache layers.
The directive takes a single argument which defines the duration of time after which the media index files will be considered stale. This is crucial in scenarios where index files may change frequently due to updates in the media segments. Setting an appropriate expiration time ensures that clients receive the most up-to-date content without unnecessary delays, while also balancing network traffic and resource utilization.
This directive can be placed within http, server, and location contexts, allowing for flexible configurations depending on different server setups or routing needs. It is essential to consider the update strategy for your media content to avoid serving outdated indices, which could lead to playback issues or poor user experiences.
Config Example
location /media/ {
pckg_expires_index 10m;
pckg_pass http://backend;
}Ensure that the duration is reasonable; too short may result in excessive caching misses, while too long could serve stale content.
Be cautious using this directive when media content updates frequently to avoid user playback issues.
