Request Flow in the Built-In WebServer

Request 1 Request 2

Tomcat – The Built in Web Server

Request 3

server.xml

web.xml


Directory Structure

CGI scope variables support

SES (Search Engine Safe) URL support

Session replication in cluster

Multiple webroot support

Output buffer size

6

Modifications to the bundled Tomcat


Modifications to the bundled Tomcat: Directory Structure

7

Directory structure matches earlier versions

Exceptions:

“Instance” replaces “Multi-Server”

Server.xml replaces jrun.xml

JRE isolated from instances, to enable common access across instances

Connector specific files isolated from the core server


Modifications to the bundled Tomcat: CGI scope variables

8

Many CGI scopes were not supported as Tomcat did not had a way to query the webserver

CGI ScopeAUTH_PASSWORD

HTTP_CONNECTION

HTTP_COOKIE

HTTPS_SERVER_SUBJECT

SERVER_PORT

SERVER_NAME

AUTH_TYPE

CERT_COOKIE

CERT_FLAGS

HTTPS_SECRETKEYSIZE


Modifications to the bundled Tomcat: SES URL Support

http://domain.com/index.cfm/about/contact/

ColdFusion Page: index.cfm

Modifications to the bundled Tomcat: Multiple webroot support

File exists in CF

webroot

Yes

No External Web Server


Modifications to the bundled Tomcat: Output buffer size

Vanilla Tomcat connector performance was low due to limitations in Output buffer size

Tomcat connector (AJP) was built to work with 8kb packet size data

In ColdFusion the Output buffer size was increased to

64kb in AJP which shown a 15% increase in the performance

<Connector port="8500" protocol="HTTP/11"

Server.xml: Default Webroot

16

<Context path="/"

docBase="<cf_home>\wwwroot"

WorkDir="<cf_home>\runtime\conf\Catalina\localhost\tmp">

</Context>

Do not forget to copy CFIDE and WEB-INF folders present in <cf_home>\cfusion\wwwroot\ to the new webroot folder


Server.xml: Virtual Directory

To add a virtual directory, uncomment context tag in server.xml

<Context path="/"

docBase="<cf_home>\wwwroot"

WorkDir="<cf_home>\runtime\conf\Catalina\localhost\tmp"

aliases="/myWebroot=C:\newwebroot\VD“ >

</Context>

Multiple virtual directories can be created with aliases aliases=“/aliasPath1=docBase1,/aliasPath2=docBase2”

Do not forget to copy WEB-INF folder present in <cf_home>\cfusion\wwwroot\ to the new webroot folder

Virtual Directory


Web.xml: Directory Browsing

C:\ColdFusion11\cfusion\runtime\conf\web.xml

<servlet> <servlet-name>default</servlet-name> <servlet-class> org.apache.catalina.servlets.DefaultServlet </servlet-class> <init-param> <param-name>listings</param-name>

Logging

19


C:\ColdFusion11\cfusion\lib\Neo-logging.xml

maxOutLogSize – Log file size

maxOutFileBackup – Number of Archives

By default ColdFusion uses “MM/dd/yy” format If you wish to change it, you can do it by changing the columns and patterns to any standard date format

<var name='pattern'>

<string>"%p","%t",%d{"MM/dd/yy","HH:mm:ss"},%a,"%m%x"%n</string>

</var>

The Apache Connector: Ubuntu

Ubuntu distributes a customized version of Apache

And does a few things differently

./wsconfig –ws apache

–dir /etc/apache2

–bin /usr/sbin/apache2ctl

–script /usr/sbin/apache2ctl

./apache2ctl needs to be specified as the Apache Binary
