Transfer Encoding An HTTP transfer-encoding type is used for application inspection decisions. The

transfer-encoding general-header field indicates the type of transformation, if any, that has been

applied to the HTTP message body to safely transfer it between the sender and the recipient.

In the Transfer Encoding field, select the type of encoding that is to be checked:

• Chunked—The message body is transferred as a series of chunks.

• Compress—The encoding format that is produced by the UNIX file compression program

compress.

• Deflate—The .zlib format that is defined in RFC 1950 in combination with the DEFLATE

compression mechanism described in RFC 1951.

• Gzip—The encoding format that is produced by the file compression program GZIP (GNU

zip) as described in RFC 1952.

• Identity—The default (identity) encoding which does not require the use of transformation.

URL URL names are used for application inspection decisions.

In the URL field, enter a URL or a portion of a URL to match. Valid entries are URL strings from

1 to 255 alphanumeric characters and include only the portion of the URL following

www.hostname.domain. For example, in the URL www.anydomain.com/latest/whatsnew.html,

include only /latest/whatsnew.html.

URL Length URL length is used for application inspection decisions.

1. In the URL Length Operator field, select the operand to be used to compare URL length:

–

Equal To—Indicates that the URL length must equal the number in the URL Length Value

(Bytes) field.

–

Greater Than—Indicates that the URL length must be greater than the number in the URL

Length Value (Bytes) field.

–

Less Than—Indicates that the URL length must be less than the number in the URL

Length Value (Bytes) field.

–

Range—Indicates that the URL length must be within the range specified in the URL

Length Lower Value (Bytes) field and the URL Length Higher Value (Bytes) field.

2. Enter values to apply for URL length comparison:

–

If you select Equal To, Greater Than, or Less Than in the URL Length Operator field, the

URL Length Value (Bytes) field appears. In the URL Length Value (Bytes) field, enter the

value for comparison. Valid entries are from 1 to 65535 bytes.

–

If you select Range in the URL Length Operator field, the URL Length Lower Value

(Bytes) and the URL Length Higher Value (Bytes) fields appear:

1. In the URL Length Lower Value (Bytes) field, enter the lowest number of bytes to be

used for this match condition. Valid entries are integers from 1 to 65535. The number in

this field must be less than the number entered in the URL Length Higher Value (Bytes)

field.

2. In the URL Length Higher Value (Bytes) field, enter the highest number of bytes to be

used for this match condition. Valid entries are integers from 1 to 65535. The number in

this field must be greater than the number entered in the URL Length Lower Value (Bytes)

field.
