CFHTTP tag

CFHTTP -- If a Mime Type (or content type) is not returned when requesting a page via CFHTTP you will

receive the following error message: The requested file is not ASCII text and can not be rendered.

ColdFusion 4.0.1 ignored the content type and displayed the page. [14372].

cfcrypt utility

The cfcrypt utility has been renamed cfencode.

Changes to Administrator

The ColdFusion Administrator Settings page has been broken into two separate pages: Settings and

Caching.

A new Locking page has been added to the ColdFusion Administrator Server section to cover the new

engine options for locking of shared scoped variables (server, session, application). For details about the

new locking options in the Adminstrator refer to New Features document.

UNIX only: Because ColdFusion no longer uses the Bristol WindU libraries, the Fast Date/Time Parsing

option has been removed from the Server Settings page. This option is no longer necessary.

Clustering

Allaire does not recommend running a mixed-version cluster. All cluster members should be upgraded to

the same version of ColdFusion.

Cluster members on Solaris and Netscape Web servers must be deleted prior to upgrading to ColdFusion

Server 4.5.1. The cluster members should be recreated once ColdFusion Server 4.5.1 has been applied.

Session-aware load balancing is enabled by default in ColdFusion Server 4.5.1.

Cluster members join a cluster in active mode by default.

Known Issues: All platforms

General

In ColdFusion Server 4.5, the "request timeout" condition became a catchable error (catchable by

<CFCATCH TYPE="COM.ALLAIRE.COLDFUSION.REQUESTIMEOUT"> or by <CFCATCH

TYPE="ANY">). In ColdFusion 4.5.1, the request timeout exception subsystem has undergone reliability

enhancements. Because of this, the "Date/Time," "Browser" and "Remote Address" diagnostic displays will

be shown on the default request timeout browser screen.

When invalid XML is encountered during WDDX packet serialization or deserialization an unknown

exception condition may be generated. This will be addressed in a future release. [15773]

Only one instance of ColdFusion can be run on any given system at a time.

Since the ColdFusion Application Server uses 32-bit signed integers to represent "integer" numeric values,

integers can only take on values in the range -2147483648 to 2147483647. When a numeric quantity

exceeds these limits, it will be stored in floating-point representation, but it cannot then be used as input to

functions, such as RandRange(), that require integral parameters.

Although Allaire recommends that you specify the scope of your variables, if you should not do so when

assigning structure fields. For example the following code will fail:

<cfscript> st1=structnew(); variables.st1.key="foo",</cfscript>

Storing client variables in the registry is not recommended by Allaire. You should store client variables in a

database or in cookies. On UNIX systems in particular, the registry is implemented as a flat text file (to

make editing easier) and reading and writing this file is slow. Even a small number of clients (less than

100) stored in the registry will significantly impact performance of the cfserver process.

CFHTTP -- If a Mime Type (or content type) is not returned when requesting a page via CFHTTP you will

receive the following error message: The requested file is not ASCII text and can not be rendered.

ColdFusion 4.01 ignored the content type and displayed the page. [14372]
