* parameter with the corresponding entry in the pcValue array containing the

* replacing the tag entirely. This allows for an implementation that does not

||||||
|
* require significant additional buffering of output data yet which will still
|
||||||
|
* offer usable SSI functionality. One downside to this approach is when
|
||||||
|
* attempting to use SSI within JavaScript. The SSI tag is structured to
|
||||||
|
* resemble an HTML comment but this syntax does not constitute a comment
|
||||||
|
* within JavaScript and, hence, leaving the tag in place will result in
|
||||||
|
* problems in these cases. To work around this, any SSI tag which needs to
|
||||||
|
* output JavaScript code must do so in an encapsulated way, sending the whole
|
||||||
|
* HTML <script>...</script> section as a single include.
