So, having got the & problem out of the way, a new document object is created in $dom and the document in $contents is loaded into it This makes the whole HTML page easily searchable using the $xpath object, which is created from $dom Next, five types of tags are searched for using the $xpath object; a href=, img src=, iframe src=, script src=, and link src= All the associated strings for each tag are then placed in the objects $hrefs, $sources, $iframes, $scripts, and $css The reason for this is that it is necessary to ensure that all links within a page are of the absolute type so that the page this plug-in returns can be served up from any server and, by grabbing all the links, it will be possible to perform a relative-to-absolute conversion on each To facilitate this, all the separate objects are then traversed, and the links found in each extracted into the array $links Then, to ensure there is no duplication of conversions, the array_unique() function is called to remove all duplicates, and the resulting set of unique URLs is then saved back into the $links array Now that the entire set of links from the document are in the $links array, a foreach loop is used to iterate through each The first part of the loop ensures there was actually a URL supplied in a link before continuing, and if so, the string variable $temp is assigned the contents of each link, but with the & symbols replaced This is so that the array $to can be assigned an untokenized URL in the next step, in which the value /$redirect u= is assigned to the current element of $to, as indexed by $count, which is incremented after each insertion After the /$redirect u=, the URL itself is attached to the end of the element, after first running it through the PIPHP_RelToAbsURL() function to ensure it is absolute So, if the value in $redirect is webproxyphp, and the link to add is http://googlecom, then $to[$count] will be assigned the string /webproxyphp u=http://googlecom Now it s time to make the link replacements within the document itself, which, as you ll recall, is stored in $contents This is done by two sets of str_replace() calls to cover the three types of links allowed in an HTML document: (1) single quoted, (2) double quoted, and (3) without quotes To do this, all href="link", href='link' and href=link statements are replaced with a unique token comprising the value of $count surrounded by two pairs of exclamation marks The first link is replaced with !!0!!, the second with !!1!!, and so on Again, I chose this as being unlikely to appear within an HTML document This process is then repeated with all occurrences of src="link", src='link', and src=link At the end of the loop there will be no URLs remaining in the document, only the exclamation mark tokens representing them And there s a very good reason for all these shenanigans, which is that the final part of this plug-in needs to convert all the links to absolute, but if it tried to do this with all the links still in place it would seriously mess up To explain why, imagine that the server being proxied is http://servercom and therefore all occurrences of /news/indexhtml must be replaced with http://server com/news/indexhtml This is all fine and dandy, but what if all occurrences of /news/ need changing too When this happens it will also impact the previous change because the newly converted http://servercom/news/indexhtml strings will get changed to http://servercom/http://servercom/news/indexhtml Do you see the problem The changes will get changed This is why all the links that need converting are first pre-processed into tokens Then all the tokens can be safely processed into the absolute URLs, without new changes modifying previous ones And that s what the next bit of code does It s a for loop that iterates through all the entries in $to (the absolute URLs) and changes each of the tokens in turn to each of the values in $to.

When > 1 there is statistical delay plus excess delay which is defined by a deterministic model For design purposes it is sufficient to estimate delays in such a system in which the statistical delay Ws is computed from the appropriate equation above with = 090 and the excess delay We is added to this from the equation below to compute total processor delay The rationale for computing the statistical delay with = 09 is that in reality as demand approached capacity the delay cannot become infinite as airline or airport operating practices will limit delay by utilizing additional servers We = T ( k ) 2 k

Once all that has been achieved, then all the links in the document will now be in absolute format, so it s safe to make a final conversion, changing any remaining !!**1**!! tokens back into & symbols, the result of which is then returned by the plug-in
