query parameters

[jason]

Hi 4INFO Team,
This is a really neat service! Thanks for making it available. I'm
looking at doing a pilot project to integrate it into my platform.

Are there any other URL query parameters besides these?
${userId}
${queryClean}

For subscription alerts, how often does the polling of my RSS feed
occur?

Is there any way to use ping noitification, rather than polling, so I
can tell your server when my alert is ready for delivery?

Thanks,
Jason

Hi Jason,

The polling of your RSS feed takes place every 30 minutes. There is no
ping mechanism.

Here is a nice easter egg for manipulating your query string:
If your queryClean string consists of "keyword param1 param2 param3"
you can do the following:
${1} will give you param1
${-1} will give you just the last param, in this case param3
${0} will give you just the keyword
${0:} is the equivalent of $queryClean
${0:2} will give you "keyword param1"
${1:-1} will give you "param1 param 2"

Thanks,
Nick
