Serving All Israeli News Web Sites from a Single EC2 instance...

Thursday, November 13, 2014, by artyom ; Posted in: Progress, Benchmarks, Framework; 6 comments

For the last year the development of the CppCMS project was less active. The vast majority of the work hours were spent on a customer's project that used CppCMS to create an outstanding advertisement system.

The project is called Linicom.

Today, when Linicom is up, running and maintained by a larger team, so I can resume the activity on the core CppCMS project itself.

Few words about Linicom:

Linicom is an engine that provides content and visitor sensitive advertisements for almost all large Israeli news web sites: including Ynet, Haaretz, Jerusalem Post, Mako, Walla and other significant web sites in Israel and abroad.

Here some interesting facts:

The system runs behind Lighttpd and uses PostgreSQL for persistent data storage. Also PostgreSQL is used extensively, all real time data is stored in memory.

Almost every request needs data processing in order to provide highly customized advertisements. In technical terms it means that almost no request can be "outsourced" to a static files - every request for every customer should be processed explicitly.

This system is probably one of the classic applications of CppCMS technology - web based system that required to be fast and efficient, being able to handle outstanding and sometimes unexpectedly changing loads without problems and provide high QoS.

Use of in-memory data storage, caching and efficient handing of the data that can't be cached is were CppCMS shines. Having a big growth potential with a minimal required maintenance and high reliability allows the to handle the business-end safely without worrying about performance issues.

CppCMS 1.0.4 Released

Monday, June 24, 2013, by artyom ; Posted in: Progress; 9 comments

This is a critical bug fix release that relates to session handing in Internet Explorer.

Added "Expires" to cookie expiration time handling that is supported by IE.

Prior to this release, cppcms session cookies used max-age option, that IE does not recognize. Starting from this release the session cookies would have both Expires and Max-Age options. All browsers that use Max-Age would ignore Expires if both given.

New options that control the session cookie properties are added, see expiration_method that would allow to alter the behavior and handle possible clock skew issues

Special thanks to Saikumar Gandapodi who reported me this issue.

Security bug fix release - CppCMS 1.0.3

Friday, January 4, 2013, by artyom ; one comment

CppCMS 1.0.3 was released today, it includes security bug fix.

This bug allowed CppCMS encoding validation to accept some invalid UTF-8 sequences which could potentially lead to various security problems like XSS and more.

It is strongly recommended to upgrade to latest version.

Note: for thous who used booster::locale::utf::utf_traits or functions booster::locale::conv::utf_to_utf directly rather than using built in CppCMS forms validation/XSS validation, you may need to recompile the application to get the updates.

The release is available on sourceforge and in the official repositories for Ubuntu oneiric, precise and quantal, Debian squeeze, Fedora 16 and 17, Centos 6 and Open Suse 11.4 and 12.1

We are under attack...

Here in Israel...

I hear explosions of Grad rockets fired by Hamas to our cities. I hear sirens that gives us short alarms to run for shelters.

This is daily routine...

What Gives Israel the Right to Defend Itself?
