firstly I don t think there is just one solution to your problem      As you know each browser is vastly differant    But lets see if we can get any closer to the answer you need      I think IE Might be easy     Check this link http   support microsoft com kb 181050  For Firefox try this   Open Firefox  and in the address bar  type  about config   without quotes   From there  scroll down to the Network http keep-alive and make sure that is set to  true   If it is not  double click it  and it will go from false to true  Now  go one below that to network http keep-alive timeout -- and change that number by double clicking it  if you put in  say  500 there  you should be good  let us know if this helps at all

For Google Chrome  Tested on ver  62   I was trying to keep a socket connection alive from the google chrome s fetch API to a remote express server and found the request headers have to match Node JS s native  lt net socket gt  connection settings   I set the headers object on my client-side script with the following options      -----    head   new headers    head append  Connnection    keep-alive   head append  Keep-Alive    timeout   1 60 5      in seconds  not milliseconds    apply more definitions to the header    fetch url        method   OPTIONS       credentials   include       body  JSON stringify data       cors   cors       headers  head    could be object literal too     cache   default        then response  gt                 catch err  gt           And on my express server I setup my router as follows    router head  absolute or regex    request  response  next   gt     req setTimeout 1000 60 5      gt        console info  socket timed out             console info  Proceeding down the middleware chain link    n n      next             Keep the socket alive by enabling it on the server  with an optional    delay on the last packet sent      server on  connection    socket   gt socket setKeepAlive true  10     WARNING  Please use common sense and make sure the users you re keeping the socket connection open to is validated and serialized  It works for Firefox as well  but it s really vulnerable if you keep the TCP connection open for longer than 5 minutes   I m not sure how some of the lesser known browsers operate  but I ll append to this answer with the Microsoft browser details as well

After the last Firefox update we had the same session timeout issue and the following setting helped to resolve it   We can control it with network http response timeout parameter    Open Firefox and type in    about config    in the address bar and press Enter  Click on the  I ll be careful  I promise   button  Type    timeout    in the search box and network http response timeout parameter will be displayed  Double-click on the network http response timeout parameter and enter the time value  it is in seconds  that you don t want your session not to timeout  in the box

I managed to find network http connect timeout for much older versions of Mozilla      This preference was one of several   added to allow low-level tweaking of   the HTTP networking code  After a   portion of the same code was   significantly rewritten in 2001  the   preference ceased to have any effect    as noted in all js as early as   September 2001        Currently  the timeout is determined   by the system-level connection   establishment timeout  Adding a way to   configure this value is considered   low-priority    It would seem that network http connect timeout hasn t done anything for some time   I also saw references to network http request timeout  so I did a Google search  The results include lots of links to people recommending that others include it in about config in what appears to be a mistaken belief that it actually does something  since the same search turns up this about config entries article      Pref removed  unused     Previously  HTTP-specific network   timeout  Default value is 120    The same page includes additional information about network http connect timeout      Pref removed  unused     Previously  determines how long to   wait for a response until registering   a timeout  Default value is 30    Disclaimer  The information on the MozillaZine Knowledge Base may be incorrect  incomplete or out-of-date
