--- title: Serve personalized and targeted content, improve security with authentication and enable caching and analytics with Customer HTTP Headers description: "A web page app that allows for passing custom HTTP header values enables your end users (digital signage managers/operators) to achieve advanced, dynamic, and highly personalized content delivery.\nThis feature moves beyond simply displaying a static webpage, allowing the signage player to send specific, non-standard information about itself or its context to the web server hosting the content. The server then uses this information to deliver a uniquely tailored response." --- [Skip to content](https://help.displaynow.io/help/custom-web-page-headers-pushed-to-digital-signage#main-content) English Show submenu for translations [Submit a Request](https://help.displaynow.io/help/kb-tickets/new?hsLang=en) [![Display NOW Support](https://help.displaynow.io/hs-fs/hubfs/Display%20NOW%20Support.png?width=225&height=44&name=Display%20NOW%20Support.png)](https://displaynow.io/) - [Platform Status](https://status.displaynow.io/) - [Knowledgebase](https://help.displaynow.io/help) - [Manager](https://manager.displaynow.io/) - [displaynow.io](https://displaynow.io/) - Submit Request Open main navigation Close main navigation - [Platform Status](https://status.displaynow.io/) - [Knowledgebase](https://help.displaynow.io/help) - [Manager](https://manager.displaynow.io/) - [displaynow.io](https://displaynow.io/) - Submit Request - English Show submenu for translations - [Submit a Request](https://help.displaynow.io/help/kb-tickets/new) 👋 How can we help you? - There are no suggestions because the search field is empty. 1.

[Media Content Set up](https://help.displaynow.io/help/media-content-set-up?hsLang=en) December 12, 2025 # Serve personalized and targeted content, improve security with authentication and enable caching and analytics with Customer HTTP Headers ## Our web page app that allows for passing custom HTTP header values enables your end users (digital signage managers/operators) to achieve advanced, dynamic, and highly personalized content delivery. #### Available in our [Web Page](https://manager.displaynow.io/user-media-app/web-page?mediaAppId=1&returnUrl=%252Fmedia-app%252Fstore%253FtotalRecords%253D244) app. Requires App v112+. #### **![Screenshot of custom header values in the web page app.](https://help.displaynow.io/hs-fs/hubfs/Screenshot%202025-12-12%20at%209.21.54%20AM.png?width=670&height=190&name=Screenshot%202025-12-12%20at%209.21.54%20AM.png)** #### **🎯 Serve Personalized & Targeted Content** Custom headers are an excellent way to **localize and personalize** content without complex API integrations or changes to the webpage's URL. - **Location-Specific Content:** End users can set a custom header like X-Location-ID: 1005 or X-Store-Name: Midtown-Mall. The web server receives this ID and automatically populates the webpage with relevant content, such as: - **Local Promotions:** Displaying sales or offers specific to that store. - **Local Inventory:** Showing real-time stock levels for that location. - **Local Announcements:** Presenting region-specific news or events. - **Device/Player-Specific Content:** Headers can communicate unique details about the display or player. - **Screen Orientation:** A header like X-Orientation: Portrait ensures the server delivers a CSS/HTML layout optimized for the vertical screen, overriding any default layout. - **License/Player Identification:** A header like X-Player-UUID: abc123def456 can be used for server-side licensing checks or for logging which specific player is requesting content. - **Audience/Time-Based Targeting:** While scheduling handles time, a custom header can dynamically influence content for a specific audience. For example, a header could signal that the screen is in a staff breakroom (X-Audience: Employee) versus a lobby (X-Audience: Visitor), prompting the server to deliver internal metrics or a company newsletter, respectively. --- #### **🔒 Improve Security and Authentication** Custom headers can serve as a simple, yet effective, layer of security for restricting content access. - **Token-Based Access:** End users can pass a secret key or token using a header like Authorization: Bearer \[custom-token-here\]. - This token is not visible in the public URL (unlike a query parameter) and is only available via the web page app, allowing the server to **authenticate** that the request is coming from a **verified digital signage player** and not a standard web browser. - The server will only deliver the content if the custom token is valid. --- #### **📊 Enable Advanced Caching and Analytics** The header information helps the server make better decisions about data management and reporting. - **Smarter Caching:** Headers can instruct content delivery networks (CDNs) or proxy servers on how to manage the content.3 For example, a header that includes a unique identifier for the content version can help ensure the display always pulls the latest update, improving performance and accuracy. - **Detailed Reporting:** The server-side application can log the custom header values for enhanced analytics. Instead of just seeing an anonymous request, the end-user's analytics platform can track and report: - "How often was the content viewed on screens with X-Location-ID: 1005?" - "What was the uptime for players with X-Orientation: Portrait?" In essence, passing custom header values transforms a generic **Web Page** display into a powerful, two-way **Dynamic Data Integrator**, allowing your end users to inject critical context into the content request, which the content server can use to deliver a fully customized experience.
