| Caching significantly increases your site's performance by keeping a local copy of each feed.

| If your web server must go through a proxy server to access other internet sites, CaRP can be configured to use it. Password protected proxy servers are also supported. | ||||
| HTTP redirects | Yes | Yes | Yes | |
| If a feed gets moved and the publisher provides a redirect, CaRP will find it without requiring you to adjust your code. | ||||
| You specify which HTML tags to allow, and CaRP will remove all others. | ||||
| Remove JavaScript handlers | Yes | Yes | Yes | |
| CaRP automatically removes potentially dangerous JavaScript handlers such as "onClick" before displaying feeds. | ||||
New features can be added to CaRP Evolution using plugins (ie. it can "evolve").
The following plugins are included with CaRP Evolution:
The following plugins are included with CaRP Evolution:
- Access Keys: Adds "access keys" to the headline links.
In most modern web browsers,
this enables the links to be selected or "clicked" from the keyboard without using the mouse.
Provides various methods for choosing and displaying access keys.
- Age Format: Enables you to vary the visual formatting of items based on their timestamps.
For example, you might display the headline and full description for items less than an hour old,
the headline and up to 200 characters of the description for items less than 6 hours old,
and just the headlines of the rest.
- NEW! Click: Redirect headline clicks through your own script (eg. to track which items get click the most).
- NEW! Expander: Make descriptions collapsable with "show more" and "show less" links.
- Filter: Provides more complex filtering capabilities than CaRP's native filterin and filterout settings,
including regular expression matching, AND, OR, NOT, etc.
- Flex Format: Enables you to vary the visual formatting of different items in the same newsfeed.
For example, you could display the headlines and descriptions of the first 3 items, but only the headlines of the rest, change the fonts, etc.
- NEW! Group Date: Group feed items by date.
- Hours Ago: Enables the display of relative times such as "3 hours ago" for item and channel datestamps.
- mySQL: Stores parsed newsfeed items in a mySQL database for use by other applications.
- Newer Than: Instead of limiting display to a specific number of items from a newsfeed, display all items newer than a specific time.
- NEW! Numeric Entities: Convert numeric entities (eg. Ӓ) to UTF-8 characters.
- NEW! Page: Enable visitors to navigate through the items in a long feed or aggregate feed a page at a time.
- NEW! Podcast: Display podcast audio in a Flash-powered on-page MP3 player.
- NEW! Processed Data: Return parsed and optionally fully processed data from the feed in an array for easy access to each part of the data.
- NEW! QuickTime: Display QuickTime and MPEG videos.
- Replace Text: Modifies the contents of a newsfeed before displaying it.
Expand acronyms, add bold or italics to certain words or phrases,
"bleep" language you don't want appearing on your site, etc.
- NEW! Sort: Sort feed items by date, alphabetically, and more.
- NEW! XML Encode: Prepare data for output in an XML document -- this plugin works with the RSS 2.0 theme to generate RSS feeds.
- NEW! YouTube: Display YouTube videos on your site.
