Redirects vs. "true" page hits : A Crawler's perspective
**Background :** 

Site domains such as bit.ly, ow.ly instagr.am, and gowal.la are shorteners which forward elsewhere .  Since most of thes url's actually forward to other, third party sites, Im assuming they can handle a pretty heavy load - that is: 

**Question :**

Is there a different politeness metric when crawling 301 redirects from a single domain (i.e. ow.ly) , compared with crawling "real" content pages (i.e. blogger.com/)  ?

More concretely : How many times a day is it okay to hit (for example) bit.ly from the same server, given the fact that bit.ly is simply running a "301 redirect" when it is hit, so the bandwidth is relateively low?  

**Some initial thoughts :**

 - My initial guess would be (10E6 = 1,000,000), given that what i see online suggests that hitting a mature site at the order of 10E3-10E5 times a day is not a huge issue, considering that large site like tumbler receives around (10E7 = 10,000,000+) views per day, with sites like google are on the order of 10E8 (billions) of view per day.  

In any case, I hope this very raw bit of fact-finding that I've done will spur some thoughts on defining the difference in "politeness" metrics when we are discussing 301 redirects versus "true" page crawls (which are bandwidth intensive).
