116: * URL encode unsafe characters. See RFC 1738.
117: *
118: * Copies src string to dst, encoding unsafe or reserved characters
119: * in %hex form as it goes, and returning a pointer to the result.
120: * The result is always a nul-terminated string even if it had to be
121: * truncated to avoid overflowing the available space.
122: *
1.53 cgd 123: * This url_encode() function does not operate on complete URLs, it
124: * operates on strings that make up parts of URLs. For example, in a
125: * URL like "ftp://username:password@host/path", the username, password,
126: * host and path should each be encoded separately before they are
127: * joined together with the punctuation characters.
128: *
129: * In most ordinary use, the path portion of a URL does not start with
130: * a slash; the slash is a separator between the host portion and the
131: * path portion, and is dealt with by software outside the url_encode()
132: * function. However, it is valid for url_encode() to be passed a
133: * string that does begin with a slash. For example, the string might
134: * represent a password, or a path part of a URL that the user really
135: * does want to begin with a slash.
136: *
1.38 perry 137: * len is the length of the destination buffer. The result will be
138: * truncated if necessary to fit in the destination buffer.
139: *
1.45 cgd 140: * safe_chars is a string of characters that should not be encoded. If
141: * safe_chars is non-NULL, any characters in safe_chars as well as any
142: * alphanumeric characters will be copied from src to dst without
143: * encoding. Some potentially useful settings for this parameter are:
1.38 perry 144: *
1.45 cgd 145: * NULL Everything is encoded (even alphanumerics)
146: * "" Everything except alphanumerics are encoded
1.38 perry 147: * "/" Alphanumerics and '/' remain unencoded
148: * "$-_.+!*'()," Consistent with a strict reading of RFC 1738
149: * "$-_.+!*'(),/" As above, except '/' is not encoded
150: * "-_.+!,/" As above, except shell special characters are encoded
151: *
1.53 cgd 152: * encode_leading_slash is a flag that determines whether or not to
153: * encode a leading slash in a string. If this flag is set, and if the
154: * first character in the src string is '/', then the leading slash will
155: * be encoded (as "%2F"), even if '/' is one of the characters in the
156: * safe_chars string. Note that only the first character of the src
157: * string is affected by this flag, and that leading slashes are never
158: * deleted, but either retained unchanged or encoded.
159: *
1.38 perry 160: * Unsafe and reserved characters are defined in RFC 1738 section 2.2.
161: * The most important parts are:
162: *
163: * The characters ";", "/", "?", ":", "@", "=" and "&" are the
164: * characters which may be reserved for special meaning within a
165: * scheme. No other characters may be reserved within a scheme.
166: * [...]
167: *
168: * Thus, only alphanumerics, the special characters "$-_.+!*'(),",
169: * and reserved characters used for their reserved purposes may be
170: * used unencoded within a URL.
