Let's say an email is sent from party A to B.  Let's refer to the set of headers that B views as Headers 1.  Party B then replies to or forwards the email to party C.  Let's refer to the set of headers that C views as Headers 2.  Does any information from Headers 1 persist separate from or as a part of Headers 2?
I am wondering if when an email is forward does it lose its original headers?

How should self-deletes be evaluated in the question ban algorithm? A self-deleted post is often not a low-quality post and may simply be a mistake noticed by the user, unlike moderator- or community-deleted posts which may indicate serious problems that the user may not recognize or may have intentionally posted.  Should they carry less weight in the question ban algorithm? "Out of pocket"? I'm increasingly hearing the phrase "out of pocket" used in America as a colloquialism to mean "away from the office", "unavailable", or "incommunicado".     I apologize for not replying sooner; I have been out of pocket.    What is the etymology of this usage? It always sounds odd to me, since I had previously always associated the phrase with expenses, e.g., "I had to pay for the service out of pocket," meaning, "I had to pay for the service using my own money." Should either of these usages be avoided? What is the extent of their acceptance? Multiple domains for different products? I have a website with software applications. Is it good for SEO to choose one keyword rich domain name for each of our software products or should we stick to a single domain?  From a user's perspective I think it would be easier to remember a domain that is keyword rich as the user will instantly know what this product is for.  But I have read articles that the latest trend in SEO is to stick to one domain for all of your products and invest on this single domain website.  Is that true? What do you advise? Should I register a separate domain for each of our products or should I use only one single domain?  Should I do a 301 redirect with a .htaccess to a single domain? And what about the sitemaps? Should I register all sites in Google Webmaster Tools and post a separate sitemap for each one of them? should my main site sitemap include all pages or should separate domains have their own sitemaps?

Where do you go for the 'nearest railroad' in Monopoly? In the American edition of Monopoly, there is a Chance card that says:  Advance token to nearest railroad Pay owner twice the rental to which he/she is entitled. If railroad is unowned, you may buy it from the bank.   However, is this the closest railroad, or the next one? If you are standing on the Chance spot in the light blues, do you go all around the board to Reading, which is the closest to you, or do you go to Pennsylvania, which is the first one you land on? File being used by another process after using File.Create() Trailing characters stripped from titles bypass length minimum Prevent text selection after double click "To be subject to" vs. "to be subjected to" I read an article from  today which stated:     TTC workers are subject to alcohol and drug testing.   A later paragraph of the same article repeated it, except it used subjected to instead of subject to.  I have rarely seen the use of subjected to before. Is it legitimate in English as well? Why didn’t the author just keep it consistent by using subject to throughout the article? Does using varieties of forms enrich the expressions within an article?

We all know that in an idealised world all objects accelerate at the same rate when dropped regardless of their mass.  We also know that in reality (or more accurately, in air) a lead feather falls much faster than a duck's feather with exactly the same dimensions/structure etc.  A loose explanation is that the increased mass of the lead feather somehow defeats the air resistance more effectively than the duck's feather.  Is there a more formal mathematical explanation for why one falls faster than the other? Looking for story title - younger gen waters down age-slowing drink of older gen, crammed into small apartment I remember a short story in which multiple generations of people being crammed into a small apartment in a city. The magical drink that either reduced or completely stopped aging was something like a soda that came in a six pack. The story focused on visual aspects of the drink at some point. The younger family members complained that their elders were living too long and apparently decided to water down the soda, I think that conclusion was ultimately left up to the reader. Many thanks for any help tracking down this story, might be one of Kurt Vonnegut's perhaps? I'm trying to perfectly overlap two images, one complementary of the other, but apperas a white stripe in the conjunction of the path, all points are perfectly aligned how can I fix? Why doesn't a commutator cause the rotation to reverse periodically or stop? I understand the field magnets attracting/repelling the armature/coil so that it turns one half-turn and then, because the commutator is turned, its contact with the brushes has switched sides, and the current goes in the opposite direction, reversing the electromagnetic polarity. Then, because the polarity is swapped, it attracts/repels to complete the second half-turn. The thing is, isn't it a bit of a gamble that it will turn in the same direction? Couldn't the it just be pulled/pushed back, more or less undoing the half-turn?  I'm also a bit confused how the rotation doesn't just stop once the commutator is oriented so that the brushes are contacting both sides of the commutator. In other words, there's a brief period just as the commutator switches the current directions where each both the brushes are in contact with both sides of the commutator where the current is neutralized. Shouldn't this stop the motor?    For reference, I'm just talking about a simple DC motor. ActiveResource timeout not functioning
