HTTP to HTTPS redirect in .htaccess

Web servers : Apache + nginx

Redirecting from HTTP to HTTPS, when the web server serving the pages is behind a load balancer or reverse proxy. Server configuration:

  • Apache + nginx;
  • SSL is enabled;
  • SSL-certificate is purchased, approved and installed.

That is, everything is up and running. So it is just the HTTP to HTTPS redirection that is left to get ready and start up. Directives for .htaccess file:

RewriteEngine On

RewriteCond %{HTTP_HOST} !^www\. [NC]

RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

RewriteCond %{HTTP:X_FORWARDED_PROTO} !https [NC]

RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

HTTP to HTTPS redirect

-- Enable runtime rewriting engine:

RewriteEngine On

-- If domain name has no www:

RewriteCond %{HTTP_HOST} !^www\. [NC]

-- Then replace it with domain with www:

RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

-- If HTTPS is not present:

RewriteCond %{HTTP:X_FORWARDED_PROTO} !https [NC]

-- Then replace domain without HTTPS with domain with HTTPS:

RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

Notes

1. X_FORWARDED_PROTO may instead be called X-Forwarded-Proto or even else. The point is to obtain the information from a load balancer or reverse proxy on the original request it gets. Load balancers or reverse proxies may provide the web server with this info and a header named X_FORWARDED_PROTO or X-Forwarded-Proto or else may be sent, holding the protocol string. It is most often so, but not always. So it should probably be determined by practice how to get the protocol string in a particular case.

2. The other way is just to set the environment variable (if it is suitable for the given web server):

SetEnvIf X_FORWARDED_PROTO https HTTPS=on

Then directives for .htaccess file are to be like this:

RewriteEngine On

SetEnvIf X_FORWARDED_PROTO https HTTPS=on

RewriteCond %{HTTP_HOST} !^www\. [NC]

RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]

RewriteCond %{HTTP:HTTPS} !on [NV]

RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

Arachne. Graphical web browser for DOS

 

Jump to: Arachne web browser. Installing and setting up for internet connection via Ethernet Arachne web browser. Installing and setting up for dial-up internet connection Versions : Configuration and use : Download links Arachne is a full-screen graphical web browser for DOS on PC computers. Originally developed by Michael Polák. First release - 22th December 1996. The last Arachne version by Arachne Labs was released on 22th January 2001. Arachne source code was opened in November of 2003 and the subsequent versions are released under GNU GPL license. Arachne is distributed as a software suite containing, besides web browser, built-in e-mail client, FTP, internet connection wizard, WAV files player. More add-ons are available: image viewer, PDF, file managers, mplayer, Telnet client, IRC and more. Arachne supports Windows-1251 and KOI8-R Cyrillic after additional packages are installed. Internet connection is via serial ports (COM) and Ethernet. There are also Arachne for Linux / SVGAlib. Versions GPL versions of Arachne. The main line of Arachne development. Major changes and updates take place within its framework. Maintained by a group of enthusiasts who also develop GPL version for Linux / SVGAlib. Arachne Labs versions. Arachne Labs, xChaos software initially, were the main structure engaged in development of Arachne until 2003, when Arachne source code was opened and the GPL versions of the browser became the main line. The last Arachne Labs version was released on 22th January 2001: Arachne 1.70 Release 3. Ray Andrews version. A GPL Arachne variation. PTS-DOS version. Similar to the corresponding versions of Arachne, but to some extent integrated with the PTS-DOS distribution. DR-WebSpyder. Based on Arachne. Basically - different web browser, for which Arachne is just an ancestor. Later the browser was renamed as Lineo EmBrowser. Configuration and use Arachne web browser was created in DOS and for DOS (the Linux version stands somewhat apart). Therefore, even though Arachne will run under many versions of Windows, Windows XP for instance, it is working under DOS when Arachne qualities are revealed best. Arachne web browser works in all major DOS variants, for example MS-DOS, FreeDOS or PTS-DOS. System requirements are low. The minimum: 80x86 CPU, 500 KB DOS base memory, 1 MB XMS/EMS memory, 512 KB SVGA video, 5 MB HDD space. Although requirements for using maximum screen resolution, maximum color depth are higher. But in this case too they are extremely small by today's standards - 486, better Pentium I computer, 640 KB base memory, 8+ MB XMS/EMS memory, 2+ MB SVGA video. Yet it depends - using 640x480 screen resolution, installing Arachne on RAM disk let to have Arachne running quite well on 386 CPU computer; if only there are enough of RAM and video adapter capabilities. Besides traditional hard disk installation, DOS LIVE CD by Roman Karpach may be used ( www.fdd5-25.net/doslivecd ), where Arachne web browser is among the software present. The characteristics of Arachne web browser installation process make the main settings be set right from the beginning. These settings for the most part are the responsibility of operating system on computers running Windows, Mac OS X or Linux, but in DOS Arachne browser takes care of everything itself.

Arachne web browser. Installing and setting up for dial-up internet connection

 

A : Installing Arachne web browser on a disk created in RAM - Arachne runs the fastest this way. RAM size should allow for a RAM disk of 6 MB or more. In order to install and set up Arachne web browser for dial-up internet connection, there have to be several programs at hand: 1. Arachne web browser [ Download ] 2. If Arachne web browser is to be used for surfing web pages with character encoding other than Latin for West European languages, visit www.glennmcc.org/apm/ to find available character set packages and download the necessary one. 3. Mouse driver, mouse.com for instance [ Download ] 4. Archivers. For example, PKZIP [ Download ] and PKUNZIP [ Download ] 5. If it is not MS-DOS 6.0+ to be used, QEMM97 [ Download ] 6. If it is not MS-DOS 6.0+ to be used, TDSK [ Download ] Installing and setting up Arachne web browser, step by step: 1. Create a RAM disk. Which drive letter will be assigned to it comes from the assumption that A: and B: go to floppy drives (even if there is only one, both letters will be reserved anyway), C: goes to the first active primary MS-DOS partition on the first physical hard disk. If there are more disks, then there will be as many letters used consecutively as to name them all. Unless there are no devices installed using DRIVER.SYS or similar drivers, the next drive letter will be assigned to the RAM disk. In order to be sure, after having the relevant string for making RAM disk added to CONFIG.SYS (See below), computer could be restarted and what letter is assigned to the RAM disk checked by experiment. In this case, it is E: Depending on RAM size it needs to be decided how many megabytes can be reserved for RAM disk. Basically, the more the better. Since, for instance, web browser cache is going to swell during prolonged and intensive use within a session. In this example the RAM disk is 12 000 KB. The maximum size for RAMDRIVE.SYS MS-DOS driver is 32 767 KB, the one of TDSK - 64 MB. In order to create such a disk, the string has to be added somewhere in the middle of CONFIG.SYS as follows: DEVICE=C:\DOS\RAMDRIVE.SYS 12000 512 512 /E 2. Create a folder, for example C:\DRIVERS\. Put there a mouse driver, for instance mouse.com 3. Add a string starting mouse driver to AUTOEXEC.BAT. Specify there the full path to the driver, may be any: LH C:\DRIVERS\MOUSE.COM 4. Run MemMaker or OPTIMIZE from QEMM97 to optimize base memory management. If it is MemMaker, press Enter at any suggestion - MemMaker will handle it itself. Computer is going to restart several times, each time MemMaker will be re-running - again nothing, just Enter, is a safe choice. If it is QEMM97 (specifically OPTIMIZE), then there is going to be several restarts too and each time just pressing Enter is OK. 5. Start installation of Arachne web browser on RAM disk. In the case discussed it is E: A195GPL.EXE Press Y to continue: Press N to specify the path to the folder Arachne web browser is to be installed in: Specify the path to the folder Arachne web browser is to be installed in. In the case discussed it is E:\ARACHNE\.
