<a id="Web Apps" name="Web Apps">Web Apps</a>

Web apps consist of two parts: user interface displayed in the web browser and the app itself.

<a id="Web Browser" name="Web Browser">Web Browser</a>

Your users can use a web app in one of the following browsers for these platforms:

<thead> </thead> <tbody> </tbody>

	Windows	OS X / OS X Server	Linux	iOS	Android	Raspberry Pi
Browser	Chrome 37+ Firefox 17+ Internet Explorer 9+ SSL requires 11+ or <a href="#SSL">settings change for 9+</a> Edge	Safari 6.0+ SSL requires 7.0+ Chrome 37+ Firefox 17+	Chrome 37+ Firefox 17+	Mobile Safari	Chrome for Android	Raspbian Web Browser

<a id="Security" name="Security">Security</a>

For <a id="SSL" name="SSL">SSL</a> with IE 9 or 10, you may need manually enable TLSv12 with these steps:

1. Select "Tools" ↠ "Internet Options". Depending on your IE settings, the "Tools" menu may be a gear icon in the upper right hand corner.
2. Go to the "Advanced" tab. 
3. Scroll down to the "Security" section. 
4. Locate and check "Use TLS 1.2" in the Security section.
5. Then, press the "OK" button.

You may need to close and reopen all open browser windows in order for these new settings to take effect.

<a href="http://blog.xojo.com/microsoft-is-killing-internet-explorer-8-9-and-10" target="_blank">Microsoft no longer supplies security updates to IE 9 and 10 for most users</a>, so you may want to consider upgrading to IE 11 or using a different browser.

<a id="Web Server" name="Web Server">Web Server / Deployment</a>

Web apps can be deployed to servers with these requirements:

<a id="Linux Information" name="Linux Information">Linux Information</a>

Because various Linux distributions have different libraries installed by default, you may need to install additional libraries before your Xojo apps will run on Linux. At a minimum, Xojo requires these Linux libraries:

<thead> </thead> <tbody> </tbody>

Always Required	Required for Desktop	Optional
glib 2.0	GTK+ 2.20	libwebkitgtk-1.0.0 or libgtkhtml (HTMLViewer) Ubuntu install command: sudo apt-get install libwebkitgtk-1.0.0
glibc-2.11 (32-bit) glibc-2.14 (64-bit)		libsoup 2.4 (Xojo.Net.HTTPSocket)
libstdc++.so.6.0.13		GTK+ 2.32 for Picture.Open Horizontal and Vertical resolutions.
libicu 4.2+

<a id="64-bit Configuration" name="64-bit Configuration">64-bit Configuration</a>

For best results, create 64-bit Xojo apps for distribution on 64-bit Linux systems. If you have to distribute a 32-bit Xojo app on a Linux distribution, you need to ensure that the 32-bit libraries are installed. They are not installed by default, so you'll have to install them manually. Below are some commands that might be helpful.

<thead> </thead> <tbody> </tbody>

Debian/Ubuntu/Mint	CentOS/Fedora/OpenSUSE
sudo apt-get install ia32-libs sudo apt-get install ia32-libs-multiarch	sudo yum install ia32-libs sudo yum install ia32-libs-multiarch
sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install ia32-libs-multiarch	sudo yum install glib2.i686 libgcc.i686 libstdc++.i686
sudo apt-get install libicu52:i386 sudo apt-get install libicu52 sudo apt-get install libicu48:i386	sudo yum provides missinglibrarypathorname sudo yum install packagenamewithlibrary
Ubuntu 14+: sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 libglib2.0-0:i386 libsoup2.4-1:i386 libicu52:i386 libgtk2.0-0:i386	/usr/bin/yum -y install glib2.i686 libgcc.i686 libstdc++.i686
sudo apt-get install libgtk2.0-0:i386	yum install libicu.i686

If you are still having trouble identifying necessary libraries, the ldd command might help. You can run from Terminal in the Xojo directory to return a list of libraries required by Xojo and their status on the system:

ldd Xojo

Most recent Linux distributions have <a href="http://site.icu-project.org" target="_blank">libicu</a> installed, but depending on the Linux distribution you may need to install it yourself. These command may be helpful:
