As the generated header data?

Trying to figure out where and how the data generated headers.
Usually the data can be pulled from the html or are they generated queries.

In this situation do not understand the origin:
- x-mag09e7sc-a:
- x-mag09e7sc-b:
- x-mag09e7sc-c:
- x-mag09e7sc-d:
- x-mag09e7sc-f:
- x-mag09e7sc-z:

Can't find this data in html, and also look at Network requests before it, and find how to get the data.

Link to url: link

Prompt where to dig further and where to look for the generated data.

The headers are part of HTTP Protocol, which consists of them from the request body. HTML about which you speak is in the request body, and headers usually ignore. Giving this data to the server and it generates them in response. When prompted for a server you form the request headers
@diana , In the end, it is not clear where these data were generated. I watched all headers before network request, and was not observed to have the server return those headers on the contrary in this query they are and where they come from...... - Ubaldo commented on April 19th 20 at 12:30
@Ubaldo, well, like I said - if this request is that the request headers set by the client, if the response headers response puts the server. Where are the request headers - handles to rummage through miles of JS) - diana commented on April 19th 20 at 12:33
@diana, this is a request. the headers should put me. question where do they come from do not understand. Usually I easily found how and where these are, or in the html page, some kind of token transfer need, or before the actual request is PRE the request to get tokenŠ° and again it is logical and easy to understand where to take it. Here the situation is such that I do not know where are these data and have already shoveled more than one day this site and have come to ask the experts. - Ubaldo commented on April 19th 20 at 12:36
@Ubaldo, we can only sympathize - there is obfuscated scripts) Senior I think I could for an hour, but it costs money. And so there all the necessary information there, instead of just you then no one will go to pick your security admin mobile operator - diana commented on April 19th 20 at 12:39
@diana, well, at least just tell me where to go to find)) did Not observe here obfuscated data. Where did you see them? - Ubaldo commented on April 19th 20 at 12:42
@Ubaldo, scripts - diana commented on April 19th 20 at 12:45

Hint: the file has the name, content and attributes. In the file somewhere, for example, the time of its creation? No. It is in the attributes.
Similarly, the contents of the response headers (!important! request headers forms the client) generates something active that gives html. For example, a header can be substituted in the web server.
For example with nginx:

location some-location {
add_header X-my-header my-header-content;
@Jaylin.Bernier usually I easily found the transmitted data, and then are faced with the fact that I can't find where they are generated to take and pass. Several days tormented. - Ubaldo commented on April 19th 20 at 12:32
