For documentation, and future references, explainthe relevance of this entry with your policies.

Profiles

Specify the Profiles applicable for this entry.

This entry will be applicable only if the connection has any one of the specified profiles.

Leave it Blank, to apply for all connections irrespective of any applied profile.

To avoid application to a connection that has a profile, use negated profile (!profile).

Specify regular expression matching the MIME-type's for which this entry is applicable.

According to their nature and format, MIME-type is a way of identifying files on the Internet.

It is highly advisable that you set this to some mime-type; otherwise all files will be checked.

Example: text/html, ^image/, ^application/, application/x-shockwave-flash.

Pattern

A regular expression pattern matching the area of text inside the file, 'to modify'.

This may be trailed with a '/' followed by flag characters like in Perl to modify options used to compile the regular expression, and must be if a '/' is used anywhere else in the regular expression.

Replace

Specify the replacement text to use in place of the area of text matching the pattern mentioned in the above field.

It may contain back references to strings captured using parenthesis in the pattern.

Applies to

This option is to select what the rewrite entry applies to.

  • BODY : Rewrite the body of the webpage or file.
  • CLIENT : Rewrite the client header, this happens before Middleaman parses it so be careful not to remove any headers needed to handle the request properly.
  • SERVER : Rewrite the header from the remote web server, same conditions from client header apply.
  • POST : Rewrite POST/PUT data sent when submitting a form or uploading a file.
