Hi @lmontesl not prerendering your pages will impact your page load speed and performance, how were you able to determine that prerendering has caused your pages to stop working?

Just to be more specific I have a custom functionallity that depends from the variable “request.header” but it stop working beacuse instead of getting the real user-agen from the visitor I get this “user-agent=CosIndex, PreRendering, hubspot, bot”

Hi @lmontesl that’s a little out of my area of expertise, have you already posted in the [Developer Slack?](https://developers.hubspot.com/slack)

there are a lot of developers in the HubSpot Community, but it can be a little quicker to find the right person to help in the Slack, just make sure you add it to the right channel and don’t cross-post, or you’ll likely get ignored 😉
