Do Not Use Symlinks in Jetty’s webapps Directory

Posted on September 18, 2013November 25, 2021 by rchapin

I set up a development instance of Jetty on my local machine and have been happily coding, compiling and deploying via a shell script. The script copies the war from my user’s target directory to the jetty users’s home dir changes the permissions and then moves it to the /webapp dir creating a symlink to the name of the .war that is referenced in a number of config files.

This was working just fine until I did a merge with → Continue reading “Do Not Use Symlinks in Jetty’s webapps Directory”

Getting Markdown Viewer To Display HTML Formatted Markdown Content in Firefox Under Linux

Posted on September 16, 2013November 25, 2021 by rchapin

I recently installed the Markdown Viewer 1.3 in Firefox 23.0 under Fedora Core 18. When I went to open a .md file in the browser it prompted me to download it.

To configure Firefox to display the markdown in the browser do the following:

Edit the ~/.mozilla/firefox/*default/mimeTypes.rdf file.

If there is not yet an existing RDF node for ‘text/plain’ add it, and add “md” as a file extension.

<RDF:Description RDF:about=”urn:mimetype:text/plain”
        NC:value=”text/plain”
        NC:fileExtensions=”md”
        NC:description=”Text Document”>
    <NC:handlerProp RDF:resource=”urn:mimetype:handler:text/plain”/>→ Continue reading “Getting Markdown Viewer To Display HTML Formatted Markdown Content in Firefox Under Linux”

Internet Explorer Not Deleting Session Cookies

Posted on September 6, 2013November 25, 2021 by rchapin

If you are trying to delete session cookies, those cookies with an expires or max-age value of -1 or no value set for that property, in Internet Explorer, you will probably notice that deleting them from the controls in the browser, does not actually delete them.

Evidently, the IE cookie implementation only writes persistent cookies to the file system and maintains the session cookies in RAM. Moreover, when telling the browser to delete the cookies, it only deletes the cookies → Continue reading “Internet Explorer Not Deleting Session Cookies”

Use CookieSpy to View and Manage Internet Explorer 9 Cookies on Windows 7

Posted on September 6, 2013November 25, 2021 by rchapin

I am doing some client-side testing of IE 9 on Windows 7 and need to be able to view cookies and their associated data.

The F12 developer tools is insufficient for this task as using the Cache/View cookie information selection only shows the cookies for the current domain that you are browsing in the current tab.

Moreover, when going to Internet Options, General Tab, clicking on the Settings button under ‘Browsing History’, and then clicking on the ‘View files’ or → Continue reading “Use CookieSpy to View and Manage Internet Explorer 9 Cookies on Windows 7”

Automate the Download of Windows VMs for Testing IE6, IE7, IE8, IE9, IE10 and IE11 with ievms

Posted on August 26, 2013 by rchapin

I am working on some client-side Javascript and I need to be able to test it in all of the currently extant versions of Internet Explorer. A collegue of mine pointed me to the ievms project by Greg Thornton (xdissent) that automates the download of multiple Windows vms provided by Microsoft to facilitate testing in multiple versions of IE.

https://github.com/xdissent/ievms

To get it working under Fedora (RedHad, CentOS):
