Uploading files will fail after ~7MB when using Windows 2008, over SSL, via a load balancer

One of the client recently encountered this issue with EPiServer CMS.

It’s very frastructing issue, my workmates spent lots of time looking from the EPiServer side, this is our perception as EPiServer had more bugs than Microsoft. However, this time we are wrong 🙂

Thanks for all my workmates hard work.

Mongo DB Shell Command – Create Database

  1. Connect to shell by running mongo
  2. To create a database, enter “Use <database_name>”  command in the shell. (The command will create a new database, if it doesn’t exist, otherwise it will return the existing database)
  3. You need to insert at least one document to make it display in the db list command. Enter “db.<document_name>.insert({name:”test”})” command to create the first document.



CQ Clientlibs debug tips


Debug clientlibs

Append ?debugClientLibs=true to write out single file and CTRL+SHIFT+U gives you tim­ing info.

Where are the gen­er­ated files stored in CQ?

They are in /var/clientlibs

When devel­op­ing I want to have sin­gle file ref­er­ences in my HTML

Enable the debug-option in the HTML Library Manager

How can I use cache-busting and clientlibs?

You can enable the hash­ing of the url via ‘ver­sioned clientlibs’.

To see a “final View” of your test page without to publish: wcmmode=disabled


How do debug CQ/AEM from Intellij 14.x

Set up a Web Facet in the Project

  1. Go to File -> Project Structure
  2. Select the “content” module (the folder contains components,templates)
  3. Click “+” above the list of modules and select “Web”
  4. As the Web Resource Directory, select the content/src/main/content/jcr_root subdirectory of your project as shown in the screen shot below.

Set up Debugger

1. Goto Intellij -> Run -> Edit Configurations -> + (Add New Configuration) -> JSR 45 Compatible Server -> Remote

2. Give the debugger a name CQ, remove any Before Launch steps (as we are not really building anything)

3. Add Application server Generic, any start page say Geometrixx English and leave everything default

4. Click on tab Startup/Connection, Debug. Change the port number or leave it default (in the below pic it was changed to 8000)


5. Restart the CQ instance with the following parameters
java -Xdebug -Xrunjdwp:transport=dt_socket,address=8000,suspend=n,server=y -XX:MaxPermSize=512m -Xmx1024M -jar cq-author-4502.jar -nofork

6. Click “Debug” icon to start the debugger from Intellij
