Add alt code to 2005/mynx and format fix README.md
Instead of the original code scanning for https (which it did not) I made the version that does an alt code. This should have been done originally but I did not think about it at the time quite unfortunately. Still it would be nice to be able to use https with it. I noted a way that one might be able to get it to work - stunnel, though it's been years since I've used it so it might not be a solution to the problem. Updated .gitignore with files in source/ subdirectory in case configure is run. To make sure that make from source/ works I copied the mynx.c to the source/ directory. I guess I could have updated the configure script but that seems like it would take more effort than it would be worth. Format fix README.md.

[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) pointed out that this

Cody changed it to scan for both http:// and https:// but the problem is a

As noted this will not work for https. This is because it does not scan for

https but also a secure connection needs to be set up before http commands can

In case someone can come up with a clever pipeline or some other hack or
|

workaround (perhaps [stunnel](https://www.stunnel.org)), Cody added the alt code

which does scan for https. Futile, maybe, in which case just enjoy it for what

Obfuscationalists to submit the missing pieces to get a functioning LAMP stack.
|
||||
Use `mynx.alt` as you would `mynx`. You'd have to specify a port at the end of
|
||||
the URL like:
|
||||
|
||||
```sh
|
||||
./mynx.alt https://www.ioccc.org:443

won't work.

[Cody Boone Ferguson](/winners.html#Cody_Boone_Ferguson) notes that, though
|
||||
probably obvious, this entry will not work with https. He changed the code to
|
||||
scan for https too (it exited before) in case someone comes up with a clever
|
||||
command line to make it work but the problem is a secure connection has to first
|
||||
be set up in order to give http commands. This is not a bug but it's worth
|
||||
pointing out as it won't work on as many websites as it used to including the
|
||||
[IOCCC website](https://www.ioccc.org) itself.
|
||||
probably obvious, this entry will not work with https. He added an alt version
|
||||
that scans for https in case someone wants to set up a pipeline or other
|
||||
workaround (perhaps with stunnel) but the problem otherwise is a secure
|
||||
connection has to first be set up in order to give http commands. This is not a
|
||||
bug but it's worth pointing out as it won't work on as many websites as it used
|
