Possible to disable Railgun for CF Worker Requests?

With Cloudflare workers we can control some Cloudflare features like we can with CF Page Rules. Example whether to minify requests

cf: { cacheTtl: cacheShort, minify: { javascript: true, css: true, html: true } }

@signalnerve any plans to add support for controlling whether Railgun is enabled or not too ?

like

cf: { cacheTtl: cacheShort, railgun: false }

Cloudflare features all plans can set on outbound requests:

  • cacheEverything :This option forces Cloudflare to cache the response for this request, regardless of what headers are seen on the response. This is equivalent to setting the page rule “Cache Level” (to “Cache Everything”). (e.g. true )
  • scrapeShield : Toggles ScrapeShield. (e.g. false )
  • polish : Sets Polish mode. The possible values are “lossy”, “lossless” or “off”. (e.g. lossless )
  • minify : Enables or disables AutoMinify for various file types. The value is an object containing Boolean fields for javascript , css , and html . (e.g. { javascript: true, css: true, html: false } )
  • mirage : Disables Mirage for this request. When you specify this option, the value should always be false . (e.g. false )
  • apps : Disables Cloudflare Apps for this request. When you specify this option, the value should always be false . (e.g. false)
  • cacheTtl : This option forces Cloudflare to cache the response for this request, regardless of what headers are seen on the response. This is equivalent to setting two page rules: “Edge Cache TTL” and “Cache Level” (to “Cache Everything”). (e.g. 300 )
  • resolveOverride : Redirects the request to an alternate origin server. You can use this, for example, to implement load balancing across several origins. (e.g. us-east.example.com )
    • Note - For security reasons, the hostname set in resolveOverride must be proxied on the same Cloudflare zone of the incoming request. Otherwise, the setting is ignored. CNAME hosts are allowed, so to resolve to a host under a different domain or a DNS only domain first declare a CNAME record within your own zone’s DNS mapping to the external hostname, set proxy on Cloudflare, then set resolveOverride to point to that CNAME record.

Hi @eva2000, no, we don’t have this on our roadmap that I’m aware of.

Could you share some details of your use case? Note that you can disable Railgun with a page rule, which might suffice.

Hi Harris :slight_smile:

Yeah the use case is when I am only on CF free plan and no more free page rules left to add an additional specific subdomain/route which needs Railgun disabled for troubleshooting a web application. Guess it would apply to any usage case where we don’t have any free slots in our page rule quota to do such on any CF free or paid plans.
