Compression¶
FusionReactor supports automatically compressing responses before they are sent to the browser. This can reduce network requirements at the cost of CPU usage.
Warning
We don't recommend using this feature any more. It can have side affects with new additions to the HTTP standard.
MIME Type Restrictions¶
MIME Type Restrictions are designed to let you specify which types of file you want to be compressed, or alternatively, which types you do NOT wish to be compressed (leaving all other file types to be compressed).
Tip
To select which mode the Restrictions page works in, change the Restrictions option on the Compression settings page.
The MIME Type Restrictions page has two main areas:
At the top of the page there is a form for you to enter new restrictions and below this is a list of all
existing restrictions for this feature.
New MIME Type Restriction¶
To enter a restriction you will need to fill the following fields:
| Configuration | Description |
|---|---|
| Request | This is the document type that you want to restrict. Firstly select if you are creating an Exact Match or Regular Expression. Next enter your MIME Type. For examples of Regular Expressions, see Regular Expressions and Content Filters. |
| Text or Regular Expression | The text input here depends on the option you choose for Request. The options are Exact Match or Regular Expression. |
Info
Once you submit the form, the page is refreshed and your new restriction will be listed in the table at the bottom of the page.
Managing existing restrictions¶
Below the Add Restriction form you will see a list of all existing restrictions. Each restriction has two icons next to it:
| Button | Description |
|---|---|
 |
Clicking this icon will change the Add Restriction form above into the Edit Restriction form, and it will be filled out with the details of the selected restriction. With this form you can change any of the information which is listed above (New MIME Type Restriction). Click Save on the right to save the modified restriction details. |
 |
Clicking this icon prompts gets you to confirm you want to delete this restriction. If you select OK the restriction is removed from the Existing Restrictions list and the page is refreshed. |
Exclude URLs¶
The Exclude URLs list lets you define a set of pages which will never be compressed. The Exclude URLs page has two main areas: At the top of the page there is a form for you to enter new exclusions and below this is a list of all existing exclusions for this feature which you can edit or delete.
New URL Exclusion¶
To enter an exclusions, complete the following fields:
| Configuration | Description |
|---|---|
| Request | This is the page you want to exclude. Firstly select if you are creating an Exact Match or Regular Expression. Exact Match Next enter the location of your page. By default the request will be an exact match and should look something like "/batchStats.cfm" or "/batch/dailyStats.cfm" (beginning with a '/' and without parameters.). The text you input here will depend on the options you choose for the Hostname and Parameters fields. Regular Expressions A good use of Regular Expressions here would be to restrict everything within a given folder. For examples of Regular Expressions, please see Regular Expressions and Restrictions. The text you input here will depend on the options you choose for the Hostname and Parameters fields. |
| Hostname | By default, FusionReactor will ignore the hostname and simply match based on the web path of a given request, but you can also opt to include it. If you enable Hostname checking then the request field should also include a hostname and look something like "productionMachine/batchStats.cfm". You should NOT include HTTP or HTTPS at the start of this string. |
| Parameters | By default, FusionReactor will ignore any parameters passed to a page, however, as with the hostname, you can also opt to include them in your restriction. With parameter checking enabled, the request field should include the necessary parameters. For example "/batchStats.cfm?period=YEAR". Once again, Regular Expressions and Restrictions can be useful here when specifying multiple possible parameter values, or even specifying parameters where the order isn't fixed. |
Info
Once you submit the form, the page is refreshed and your new exclusion will be listed in the table at the bottom of the page.
Managing existing exclusions¶
Below the Add Exclusion form you will see a list of all existing exclusions. Each exclusion has two icons next to it:
| Button | Description |
|---|---|
 |
Clicking this icon takes you to the Modify Exclusion page. From this page you can change any of the information which is listed above (New URL Exclusion). |
 |
Clicking this icon prompts if you are sure you want to delete this exclusion. Selecting OK removes the exclusion from the Existing Exclusion list and the page will be refreshed. |
Compression Settings¶
The Compression Settings page lets you turn on or off the compression features as well as letting you define how the MIME Type Restrictions behave.
Compression support¶
Warning
We do not recommend using this feature any more. It can have side effects with new additions to the HTTP standard.
| Configuration | Description | Default |
|---|---|---|
| GZIP Requests | When this option is enabled, FusionReactor will attempt to decompress HTTP requests which are sent to the server in a compressed format. | Disabled |
| GZIP Responses | When this option is enabled, FusionReactor will attempt to compress outgoing HTTP responses unless otherwise instructed by the MIME Type Restrictions or the URL Exclusions. | Disabled |
MIME Type Restrictions¶
| Configuration | Description | Default |
|---|---|---|
| MIME Type Restrictions | This value defines how MIME Type Restrictions behave. Ignore requests that match the rules - By default, all requests will be compressed when compression is enabled unless the page's document mime type matches one of the rules defined on the MIME Type Restrictions page (then it will NOT be compressed). Compress requests that match the rules - no requests will be compressed unless the page's document mime type matches one of the rules defined on the MIME Type Restrictions page (then it will be compressed). |
