The proxy supports the declaration and use of rules called path overrides (alternatively called subtree overrides). They can be used to apply a variety of changes to an exact (e.g.
/about-us.html) or prefix paths (e.g. all pages under
A project has no overrides by default. Besides the search field at the top, the “Add new path” button is available. Click on it to type or copy & paste your path/prefix. Click on the “Add path” button to the right of the row to add it to the list. The option to choose the type of the path (exact URL or prefix) is available as a dropdown.
You’ll notice that adding new paths and setting up corresponding overrides are done at two separate stages. Any path can have more than one type of override associated with it (but overrides differ in how many of each can be present on a given path).
There is a row of icons to the right of each path that you can use to edit the overrides. Click on the blue plus icon to add a new override for a path. Each type will also have another set of icons for editing and deletion.
Keep in mind:
- overrides are applied only on intra-domain paths (elsewhere called the project URL). They cannot be applied on any path referenced on an external domain.
- overrides are applied early on in the pipeline, before any translated text is inserted. They are also not target-language specific.
- query parameters (
?q=valueetc.) are not supported. Do not add them to path overrides.
- When declaring a content type, mak sure you use an exact description:
text/htmldoes not equal
text/html; charset=utf-8or vice-versa. Be specific.
- Some of the overrides (particularly search & replace overrides) become non-editable after they are saved. You’ll need to delete and re-add these rules to change them.
Important! Add/edit multiple paths and overrides at once, but remember that all changes are UNSAVED until you click on “Apply settings”! Keep an eye out for the ⚠ icons on the right, as shown in the screenshot below.
Search & Replace Override¶
Run a search & replace on the page or pages on the prefix. This lets you apply simple changes to the page source. You can choose between string or regexp replacement.
In the example above, search & replace is used to extend the list of classes for any element that possesses only the hello-world class.
The replacement field supports regexp backreferences via the
$n format, as in the screenshot above. The example looks for “aaa bbb ccc” in the page source, stores backreferences to each letter group and reverses their order, resulting in the output “ccc bbb aaa”.
Refer to the
java.util.regex.Pattern documentation for the details of the supported regular expression format.
Multiple S&R overrides can be added on the same prefix, and they will be applied sequentially. No two replacement strings/regexps may match, the dialog will display an error if you attempt to enter the same replacement rule twice.
Default Charset Override¶
This override is presented as a simple text field, the contents of which will be used for
<meta charset="..."> tags. Useful in cases where the original site is declared to be in an encoding that is incompatible with one of the target languages.
Only one charset override may be present on each path or prefix.
Override the Content-Type HTTP header for a given path or prefix. Frequently used with template URLs or JS resources with mischaracterized Content-Types, it is sometimes useful to avoid encoding or character escaping troubles.
Content-Type overrides can be added on each path or prefix, but no two such fields may match.
