Page rules can be used to customise your Peakhour settings for different sections of your site. For example you might want to customise CDN caching options for your checkout process, or pagespeed optimisation. Page rules are also ordered with the first matching rule being executed.
Configuration options
Pattern will be matched against URL path. It is possible to use * in pattern. Normally pattern is expected to start with / symbol.
Patterns are matched in order of adding, strings are case sensitive.
Examples:
//some/path/to.jpg*jpg
GZIP
Enable or disable GZIP
Websocket enabled
Support websocket protocol.
Track sessions
Set session id cookie if enabled. Allows to track what request were made by client during one session
Redirection
HTTP redirect location
Redirect to URL if set.
HTTP redirect status code
If HTTP redirect location is set then redirect with given status code
(normally either 301 (default) or 302).
Caching
CDN
Cache resources using external fetcher
CDN query mode
Criteria to use when considering and storing fetched resources and query string behaviour.
| Setting | Description |
|---|---|
| none | don't cache resources with a query string |
| full | cache resources using the full query string |
| strip | cache resources but strip the query string |
Implicit cache TTL
In seconds. Specify the lifetime of cached objects.
CDN skip cookie
Skip CDN if request has cookie matching given pattern. Pattern can contain * to match zero or more symbols and | to separate matches.
CDN remove query args
Remove given query arguments with its values from request path before looking up CDN resource. Value is comma-separated list of argument names.
Cache enabled
Enable in-memory, in-line caching of content.
Content is cached based on the Cache-Control header.
Cache subkey vars
Use additional variables to construct cache key in addition to host/path. Accepts |-separated list of key[:value] variables.
| Scheme | Description |
|---|---|
| query | cache based on query string, cache key is based on query string |
| header_present | cache based on request header present, cache key is based on header name |
| header | accepts request header name as value, cache key is constructed based on header value |
| language | cache based on Accept-Language, cache key is constructed based on first value of header |
Cache strip cookies
Strip Set-Cookie headers from stored responses and Cookie from outgoing requests to potentially cacheable resources.
Edge TTL sec
Force cache resources for at least given seconds. If resource can be cached for longer (because allowed by cache control or implicit cache ttl) then cache it for longer than given value. Zero value (default) honors origin resource headers. The value is internal and not visible to clients, they still get original headers.
Browser TTL sec
Override Cache-Control: max-age for cached contents to have at least given value. Negative value (default) honors origin resource headers. Zero value means cached resources are not allowed to be cached by clients (max-age=0). The value is not used by RP itself in any way but only returned to clients to allow browser and RP cache to store same resource for different time.
Modsecurity
Blocklists
Comma separated list of blocklists.
Modsecurity mode
Specify how the WAF reacts to security violations.
| Setting | Description |
|---|---|
| none | disable |
| enforce | send a HTTP 403 when a rule is triggered |
| warn | log the violation and allow to pass, useful for testing |
ModSecurity rules
List of rule rules to enabled.
Modsecurity removed rules
List of rule rules to skip.
Pagespeed
Pagespeed mode
Specify Pagespeed handling mode. The following options can be configured.
| Setting | Description |
|---|---|
| none | disable-pagespeed |
| full | full page rewriting |
| requests-only | serve rewritten resources but don't rewrite the page |
Pagespeed configuration
Specific pagespeed configuration directives.
Pagespeed enable rules

LUA
Lua enabled

Origin
Load balancing mode
Specify load balancing mode.
| Setting | Description |

| none | no rate limiting |
| global | use global rate limiter |
| vhost | rate limit virtual-host |
| vhost-busy | rate limit on virtualhost-busy |
| zone | rate limit to zone |
