Does Embedding/sharing URLs in Gmail Lead To Indexing?

[engine]

I've been sharing urls in gmail and i'm wondering if it is leading to the URL getting spidered and possibly indexed.

Does anyone have any clear evidence to confirm one way or the other whether the url wlll be spidered, even if it's not indexed?

I've often suspected this - sometimes it seems like it has to be - and yet when I test it by sending a gmail to myself, I don't see the crawl follow. The problem otherwise, is that if i send the email to someone with the Google toolbar installed, or a Chrome user - then if they click on the link, there goes the data off the Google via another channel.

Via public server logs?

I just have hints but no proof: Is Google spidering URLs which appear in email? [webmasterworld.com]

No evidence but I wouldn't be surprised. One could very easily attribute it to Gmail when it could be toolbar, or Chrome though.

Thanks, i'm going to run a controlled experiment and will report back if I have conclusive results.
