Software Garden SRCSVC Program
SRCSVC (a Software Garden® product) is
a program for implementing a server-based service to view the source HTML
code of a web page using a browser. It is a Perl program that runs as a CGI script on a web server. It is usually invoked
using a bookmarklet while viewing a web page. The returned HTML will be a page that shows
the source HTML that makes up the original page. The effect is similar to using "View / Source"
or "View / Page Source" in a browser, with some nice additions:
- Long lines are broken at a maximum length and wrapped, with the fragments indented appropriately.
- href= and src= attribute values are displayed as links that either popup a window (for images), or display the contents listed by this program (html pages, css and Javascript files, etc.). This is useful for looking at the files in a frameset, or reading boilerplate Javascript.
- The text is displayed in bold, with markup (tags, etc.) shown normally. This makes it easier to look through code when using the text as a guide.
- You can optionally display in "short tags" mode with most HTML tags reduced to just their names, without the attributes or their values shown (except for href and src). This form is useful when you just want to understand the basic structure of a page. Indenting is preserved.
- Values in the HTTP header are displayed below the listing. Most of these are not available in normal source listings or page info, since they come from the request itself. These include the server type, last modified date/time, cookies, etc. In addition, the protocol and status values in the response are displayed, along with the URI base. This base may be set by various HTTP/HTML means, and may be the result of redirection (and therefore not correspond to the requested URL).
- A configuration file may be used to override default values for a variety of things.
Here is a sample output:
