Are there legislative limitations on web pages mirroring?
Let me explain the task. If to publish some article with HTTP links in any web site, the source of information that has been used could be checked immediately by clicking on the links, (Wikipedia do such as to provide the changeability of objectivity of the information). However, in time the source web page that has been used as reference could be deleted, as result it becomes impossible to check the source of information. The way out is to create the mirror of source web page and include this mirror in own web site. So even if source web page will be deleted, it’s still possible to refer on the mirror.
Let me give an example of the conflict situation. Mr. A in a fit of temper published on his home page the unfavorable information in respect to himself, then later comes around and delete this information. However Mr. B, who has the interest to Mr. A, already quoted the deleted information with http-link and also just in case created the mirror of the home page of Mr. A. Although Mr. A already delated the information, Mr. B still can use the mirror to refer on source of information. All that left for Mr. A to resque his requtation is to hire the high-payed lawyer and prove the false fact that mirrored information has been edited.
OK, it was the private example, however to exhaust this theme, it’s required to consider also the conflict situations with organizations. Here is another instance. Do you remember the Snowden's exposure about global surveillance system? E. g. Mr. C going to publish the essay about these systems based on Snowden’s information on his home page. He will be refer on newspaper articles that has been published also in the internet, e. g. “The Guardian” or “The New York Times”. But if CIA threats “The New Yourk times” and demand to delete the publications about surveillance systems, of course the newspaper administration will do it. However Mr. C created the mirror of “The New York times” news page and it will be available to check if from web page of Mr. C. What will be then, I can just suppose, but let us come back to original question and discuss the law related with web page mirroring.
