MimeFilter
MimeFilter directs EZproxy to process a given file type that EZproxy does not process by default. This can only be applied to a specific database stanza.
MimeFilter is a position-dependent config.txt file that must be included after the Title directive of a specific database stanza. It allows the EZproxy administrator or content provider to specify a particular file type that EZproxy should process, that it would not otherwise process by default.
Syntax
MimeFilter mime-type URI-pattern [-] action
Where each of the following variables must be entered:
| Variable | Description | Example(s) |
|---|---|---|
mime-type |
The mime type of object to apply URL rewriting rules to. | application/json |
URI-pattern |
URIs to apply URL rewriting to. This can be a PCRE regular expression. |
|
|
|
If this variable precedes the action variable, then remove default patterns for rewrite and ONLY consider these patterns for rewrite. | - |
action |
Rewrite objects that match the above criteria that are embedded in Javascript, pdf, test, or HTML. |
Values can be:
If left blank an error is reported, and the directive is ignored. |
EZproxy v6.1 and later
EZproxy v6.0.8 introduced default support for json rewriting. Content providers and resources requiring json applications to be rewritten should no longer require the MimeFilter directive; however, leaving the directive in stanzas that previously required it will do no harm.
Example
The following example would tell EZproxy to rewrite json applications in any URL (the *. means match any URL) embedded in the javascript.
MimeFilter application/json .* javascript
This is the most commonly-seen application of this directive in a database stanza.
